Mentioning users in notifications using PSTeams PowerShell Module

Microsoft Teams over the last few years have grown into an excellent and flexible tool for both small and big companies. Having the ability to chat with users, store files or have all sorts of data in one place makes it easy and functional. Of course, it has its fair share of issues, but it's getting better. One of the cool features of Microsoft Teams is being able to send notifications to Microsoft Teams Channels using WebHook Notifications. In the beginning, this feature was pretty limited, but after a few years, it got much better with support for Adaptive Cards, List Cards, Hero Cards, Thumbnail Cards, and Office 365 Connector Card.

Finding duplicate SPN with PowerShell

Duplicate SPNs aren't very common but can happen in any Active Directory as there's no built-in way that tracks and prevent duplicate SPN's. One has to either know all SPN's in the environment, track them or check each time whether it already exists or not. Things get more complicated with larger Active Directory environments as people change, new apps are added, old apps are forgotten, but SPNs prevail.

Solving typo problems with Fuzzy Search in PSWriteHTML

One of the everyday use cases with PSWriteHTML is to create a simple view of PowerShell data in a table. While PowerShell comes with a built-in cmdlet ConvertTo-Html, it's basic in its functionality. It makes an HTML representation of PowerShell data, but it brings no CSS, JavaScript, or other functionality. While for some use cases, it's enough, the other times, you need to make an effort to make it usable.

Active Directory Domain Services could not replicate the directory partition – The replication operation encountered a database error

If you ever encounter an error while trying to create a new domain within a forest saying, "The replication operation encountered a database error," it makes you sweat a bit. Your brain tells you it will be a nightmare to fix, do I have proper backups to make it happen, and the question "why now" shows up.

Configuring Office 365 settings using PowerShell – The non-supported way

Office 365 is a huge beast. It has so many services that it's hard to track all of them. It's even harder if you want to manage Office 365 using PowerShell. Microsoft makes many different PowerShell modules available for you, such as AzureAD, AzureADPreview, ExchangeOnline, MicrosoftTeams, and recently, Microsoft.Graph. But even with so many different modules, there are still tasks that Microsoft won't let you do from PowerShell. But it doesn't mean that it's not possible to do it. I've spent some time tracking how Microsoft does things while you click thru the interface and created an O365Essentials PowerShell module that can do it in an automated way.

Encrypting and decrypting PGP using PowerShell

Some time ago, I decided that having an easy-to-use PGP PowerShell module is a way to kill my boredom. Four months have passed, and I decided to share it with the world, as it may be helpful to some of you.  Today I would like to introduce you to PSPGP - PowerShell module that provides PGP functionality in PowerShell.

Easy way to connect to FTPS and SFTP using PowerShell

FTPS and SFTP are two ways to send and receive files from remote sources. While the name suggests both do the same thing, those are different protocols, in the end, having the same goal. A few weeks back, I had to make sure I can reliably download files from FTPS server using PowerShell, and since I couldn't find anything straightforward to use, I decided to write my own. Transfertto is a new PowerShell module that supports both FTPS and SFTP protocols. Its goal is to be the only module that you need to transfer files to and from FTP/SFTP servers.

Sending email as an alias (proxy address) with Office 365

Sending emails in Microsoft Exchange world using an alias for an account has always been a pain. It required working with workarounds such as setting up Shared Mailbox or Distribution Groups and using SendAs permissions. For years admins around the world were asking Microsoft to change this, and finally, in April 2021, they did! It's a new feature of Office 365, and it requires action from Office 365 Administrator.

Advanced HTML reporting using PowerShell

I've been using HTML reporting in PowerShell for a while. Initially, I would usually build HTML by hand, but the time spent trying to figure out what works and what doesn't drive me mad. With the PSWriteHTML module, a lot has changed. With just a few PowerShell lines, I can create feature-rich reports that change how I show data to my Clients. Today I wanted to show you some advanced HTML reporting without actually complicating PowerShell code. In the last few months, I've added many features that create advanced reports without sacrificing readability.

Monitoring LDAPS connectivity/certificate with PowerShell

Some time ago, I wrote a blog post on checking for LDAP, LDAPS, LDAP GC, and LDAPS GC ports with PowerShell. It mostly works, but it requires a tad bit of effort, and it doesn't cover the full scope that I wanted. Recently (well over 3 years ago), Chris Dent shared some code that verifies the LDAP certificate, and I thought this would be good to update my cmdlets to support just that with a bit of my own magic on top.

The only command you will ever need to understand and fix your Group Policies (GPO)

I've been working on cleaning up Group Policies for a couple of months. While it may seem trivial, things get complicated when you're tasked with managing 5000 GPOs created over 15 years by multiple teams without any best practices in mind. While working on GPOZaurr (my new PowerShell module), I've noticed that the more code I wrote to manage those GPOs, the more I knew passing this knowledge to admins who will be executing this on a weekly/monthly basis is going to be a challenge. That's why I've decided to follow a similar approach as my other Active Directory testing module called Testimo. I've created a single command that analyses Group Policies using different methods and shows views from different angles to deliver the full picture. On top of that, it provides a solution (or it tries to) so that it's fairly easy to fix - as long as you agree with what it proposes.

Creating Office 365 Migration Diagram with PowerShell

A few weeks ago, I posted a concept migration diagram for Office 365 to Twitter and Facebook. Today I thought I would show you how you can do it yourself using PowerShell and PSWriteHTML PowerShell module. When I started working on this, I've thought I want to create before and after infrastructure to see how it will look when migration ends. I've initially planned to assign myself an Office 365 Visio Plan 2 license and do something manually, thinking it may be just much easier. Unfortunately for me, there were no free Visio licenses in my tenant, and my laziness took over, so I've decided to give it a go using PowerShell only.

Remove-Item : Access to the cloud file is denied while deleting files from OneDrive

I like OneDrive. It allows me to keep my data secure and always synchronized. If things go wrong, I can always get it back. I use it for almost everything. Even for my PowerShell projects, which are committed to GitHub, so in theory, I shouldn't need that. But every once in a while, I make some stupid mistake and delete a file that has yet not been committed to GitHub, and that's where the OneDrive comes in handy. Quick restore, and we're back. Unfortunately, sometimes things aren't as I would expect them to work. For example, let's have a look at this nice list of markdown files that are documentation for my module called GPOZaurr.

Introducing PSTeams 2.0 – Support for Adaptive Cards, Hero Cards, List Cards and Thumbnail Cards

PSTeams PowerShell module has been on the market for a while now. It supports sending notifications to Microsoft Teams channels via Incoming WebHooks. You could send a pretty message to the team's channel with just a few lines of code. With PSTeams 2.0, support for Adaptive Cards, Hero Cards, List Cards, and Thumbnail Cards was added.

Visually display Active Directory Trusts using PowerShell

Active Directory Trusts are useful to connect one or more domains. But as useful those are, they can be very dangerous. Also, keeping trusts working and in good shape should be a top priority for Active Directory Admins. While there is a couple of command in the Active Directory module Get-ADTrust, I thought I would try and write my own that checks a few more things. I want to thank Chris Dent for his input on the part of this command. His binary skills amaze me!

Visually display Active Directory Nested Group Membership using PowerShell

In the Active Directory PowerShell module, you have two commands to your disposal that help display group membership. Those are Get-ADGroup and Get-ADGroupMember. The first command contains property Members, which gives you DistinguishedName of all members, and Get-ADGroupMember can provide you either direct members or with Recursive switch all members recursively (skipping groups). Till a few weeks ago, I was a happy user of those commands until I noticed two things. Member property for Get-ADGroup sometimes misses elements for whatever reason.

Restoring (Recovering) PowerShell Scripts from Event Logs

A few days ago, I was asked to take a look at PowerShell Malware. While I don't know much about malware, my curiosity didn't let me skip on this occasion, and I was handed over WindowsPowerShell.evtx file. Ok, that's not what I expected! I wanted PowerShell .ps1 files that I can read and assess? Well, you play with the cards you were dealt with. What I was handed over was PowerShell Event Log. PowerShell writes whatever you execute, and it thinks it is risky, to Windows PowerShell Operation Event Log.

Mailozaurr – New mail toolkit (SMTP, IMAP, POP3) with support for oAuth 2.0 and GraphApi for PowerShell

Today, I'm introducing a new PowerShell module called Mailozaurr. It's a module that aims to deliver functionality around Email for multiple use cases. I've started it since native SMTP cmdlet Send-MailMessage is obsolete,  and I thought it would be good to write a replacement that adds more features over it as things around us are changing rapidly.

Active Directory DHCP Report to HTML or EMAIL with zero HTML knowledge

I'm pretty addicted to reading blog posts. I saw this new blog post the other day, where the author created the DHCP HTML report, and he did it by manually building headers, footers, table borders, and finally, adding some coloring to the percentage of DHCP being in use. It's the "standard" approach to build HTML in PowerShell, and I've seen a similar path before, but that got me thinking how much time it would take for me to replicate the very same functionality using PSWriteHTML module.

Getting file metadata with PowerShell similar to what Windows Explorer provides

I'm working on a new feature for one of my modules that requires me to know what kind of files I am working with. It's quite easy in PowerShell, and without a lot of code, you can reasonably quickly get necessary information about data stored on your desktop or anywhere else for that matter.

Using Win32_UserAccount WMI filter in PowerShell/Group Policies and what to avoid

Some months ago, I created PowerShell Script to create local administrative users on workstations - Create a local user or administrator account in Windows using PowerShell. It's a bit overcomplicated, but the goal was it should work for Windows 7 and up, and that means supporting PowerShell 2.0. As part of that exercise, I've been using Win32_UserAccount WMI based query to find local users and manage them to an extent. While Get-LocalUser exists, it's not suitable for the PowerShell 2.0 scenario. I also use the same query in GPO for WMI filtering. You can say it's been a good friend of mine.

Converting Pester V4 to Pester V5 basics

Now that Pester V5 is out, I decided that I need to make sure that my Pester tests for all my modules keep on running correctly. Some substantial changes in Pester add new features, changing some things, but that also means all the tests that you have defined most likely will need a small push to get it up and running again on Pester V5. Starting this blog post, I wanted to mention that I am by no means an expert on Pester, but I do use it for some time now for most of my projects.  I am using basic functionality, but even that basic functionality stops working once you upgrade from PesterV4 to PesterV5, so I thought I would save you some time and give you a small overview of how you can quickly fix it. It works for me, but you may have to find your way to fix things.

Getting Verified badge next to your GitHub commits in VS Code

A bit over two years ago, I started posting my PowerShell code as modules on GitHub. Initially, I planned to have them hosted on my website, but few people asked to post it there, and they were right. It would be fairly hard for me to keep my code up to date on my website and, at the same time, let people submit bug reports or help with some PR. It was the right decision! Now that I've worked for over two years on GitHub as a daily driver, I wanted to get a new green badge that's shown on GitHub when you edit some code. I don't know if you ever noticed, but if you write any code, text file directly via the webpage, your commits always have Verified badge next to them.

Office 365 – Limiting license to minimum apps required

Office 365 has a lot of options and applications to choose from. Enabling one E1, E3, or any other license gives the user a lot of features, including Exchange, SharePoint, and Teams.

AzureAD – Enable Password Expiration with Password Hash Synchronization

Azure AD Connect allows three ways to make sure the user password is the same in Active Directory and Office 365. Those are Password Hash Sync, Pass-Thru Authentication, and ADFS. While my preferred option to go with would be Pass-Thru Authentication, only Password Hash Synchronization is the easiest and least resource-intensive. It synchronizes user password to Office 365, and even if your Active Directory is down, you can still log in to Office 365. It's perfect for small and even more significant companies that don't have resources or can't guarantee that their infrastructure will stay 100% time online so users can authenticate based on their Active Directory.

Active Directory DFS Health Check with PowerShell

One of the critical parts of Active Directory is DFS. It allows you to share same NETLOGON/SYSVOL folders across all Domain Controllers in your Forest. Its health is vital to the functionality of your Active Directory. If it's broken, a lot of things may not work, and it's not that easy to tell the status of it. At first sight, everything may seem to work correctly, but if you take a closer look - not so much. It's great if you find it out by yourself, but not fun if suddenly GPO's don't apply to some users, computers, and you find out a year later.

Renaming NETBIOS name of Active Directory Error

Recently I was testing renaming the NETBIOS name of an Active Directory domain. While this process is fairly easy, there are a few gotcha's, and before one would like to rename their domain or NETBIOS name, serious testing is required to be sure everything works after rename.

PowerShell Modules I worked on in 2019

It's year 2020 and 365 days passed since my last year blog post about PowerShell modules I worked on in 2018. I thought it would be a good occasion to review what happened and how things changed during that time. When I wrote the last blog post in the first days of 2019, my PowerShell modules were downloaded just a bit over 15000 times. Fast Forward today, and the counter is at 280000 times spread over 40 modules. Of course, not all those modules are equal. In 2019 I created multiple new PowerShell modules, but some modules were archived, while others were migrated back to their "parents". Just to see how my community road was going in the last years I decided to check some statistics.

Sending information to Event Log with extended fields using PowerShell

Reading Event Logs is something that every admin does or at least should do quite often. When writing PowerShell scripts, you often need to read event logs to find out different things across your infrastructure. But now and then it's quite the opposite. You need to write something to Event Log so it can be recorded for the future. Sure, you can write your information to log files, but since Windows already has a built-in logging system, it may be much easier to write stuff to event log. This allows you to centralize your event logs and processed by specialized tools like SIEM.

Merging, splitting and creating PDF files with PowerShell

We're in the last days of 2019, and this will be my last blog post this year. What better way to end a good year than with the release of the new PowerShell module. If the title of today's blog post isn't giving it up yet, I wanted to share a PowerShell module called PSWritePDF that can help you create and modify (split/merge) PDF documents. It joins my other PowerShell modules to create different types of documents such as PSWriteWord, PSWriteExcel, PSWriteHTML. I know that PSWriteExcel is relatively basic, but both PSWriteHTML and PSWriteWord deliver robust build capabilities.

Sending Messages to Microsoft Teams from PowerShell just got easier and better

Christmas time is upon us, and I've decided that my PSTeams module needs some love. I wrote it in late 2018 and updated it a few times at the beginning of 2019. This release hopefully is worth of having 1.0 version number. I don't do that often and usually go for build numbers changes only, but Microsoft Teams message cards have their limits on functionality. Therefore, there are not many things that can be added unless Microsoft opens up and gives us all the cool features of Adaptive Cards. PSTeams module uses Webconnector to send messages to Teams. That method only supports Message Cards, which even Microsoft calls Legacy. But legacy doesn't mean fully functional with some cool features of their own. If you're new to PSTeams you may want to read those 2 posts below to get information how to set it up.

Getting Azure Health by parsing HTML using PSParseHTML

Some time ago I've wrote PowerShell way to get all information about Office 365 Service Health, and if you were thinking that I would try the same concept for Azure Services you were right. However, I failed. This is because Office 365 Health can be gathered using Microsoft Graph API, and Azure Health information, as far as I know, is not available in the form I wanted it. Azure Status is available as part of Azure Status website. Contrary to Office 365 health you don't have to login to your Office 365 tenant to read it.

Since I have already done similar stuff for my PSwinDocumentation.O365HealthService PowerShell module that I've described in PowerShell to get all information about Office 365 Service Health, I thought this will be easy run as I'll just reuse the code I've done for that module. As always for Graph related tasks you need to register your application and assign correct permissions. I've used my own article for that with changes to which API I want to access. Now that I've done all that I've extracted my Connect-O365Graph function from my module and started connecting.

Create a local user or administrator account in Windows using PowerShell

Recently I got a simple task to implement LAPS for the newly created local user instead of using the built-in local administrator account. It seemed easy at first. Go to Group Policies, create a new user, add it to an administrators group, and then follow standard steps to implement LAPS. That is until you find out it's actually not possible anymore due to password encryption key being available in the wild, which made Microsoft block that Group Policy Preference. While that road is blocked, I still need to get my user-created somehow. Let's do it with PowerShell. It's quite simple - use New-LocalUser a few parameters, some random password that I don't need to save as LAPS will overwrite it. Except it's not available on PowerShell 2.0, which is the default for Windows 7 that I have to support. Things get even more complicated if you consider that Administrators group is called differently in different countries. While I stopped supporting anything below PowerShell 5.1, I can't say if it's the project requirement.

Nested Tabs, Diagram Updates, Diagram Events, Calendar Object and more in PSWriteHTML

One of the new features I've worked on was connecting Diagrams with Tables. Someone suggested, and I thought it would be cool to be able to click on the Diagram node and find more details about it in a table next to it. But then I thought it would be even cooler if you could have multiple tables linked to one Diagram. For example, below, I've created two tables with Users and Computers and populated Diagram with that data.

Easy way to create diagrams using PowerShell and PSWriteHTML

A few months ago, when I was working on PSWriteWord and PSWriteHTML, I thought to myself that in 2020 if I'll get time, I'll try to create PSWriteVisio. While I wasn't sure I would be able to make it past some concept, it was in my plans for 2020. It's still 2019 though, and while working on Testimo for Active Directory Healthchecks, I thought it would be nice to have a visual representation of network, forest schema or replication. I couldn't get this idea out of my head. I thought on using PSGraph from Kevin Marquette to generate image and import that to PSWriteHTML but it was a bit tricky and PSGraph requires external software to work - and has some additional steps for Windows, Mac or Linux.

What do we say to health checking Active Directory?

Setting up a new Active Directory is an easy task. You download and install Windows Server, install required roles and in 4 hours or less have a basic Active Directory setup. In an ideal world that would be all and your only task would be to manage users, computers, and groups occasionally creating some Group Policies. Unfortunately, things with Active Directory aren't as easy as I've pictured it. Active Directory is a whole ecosystem and works well ranging from small companies with ten users to 500k users or more (haven't seen one myself - but so they say!). When you scale Active Directory adding more servers, more domains things tend to get complicated, and while things on top may look like they work correctly, in practice, they may not. That's why, as an Administrator, you need to manage Active Directory in terms of its Health and Security. Seems easy right? Not quite. While you may think you have done everything, checked everything, there's always something missing. Unless you have instructions for everything and can guarantee that things stay the same way as you left them forever, it's a bit more complicated. That's why Microsoft delivers you tools to the troubleshoot your Active Directory, such as dcdiag, repadmin and some others. They also sell monitoring solutions such as Microsoft SCOM which can help and detect when some things happen in your AD while you were gone. Surely there are some 3rd party companies give you some tools that can help with a lot of that as well. Finally, there is lo of folks within the community creating PowerShell scripts or functions that help with some Health Checks of your Active Directory.

Making PowerShellGallery modules Portable

I'm a big fan of PowerShellGallery. It's easy to use, Microsoft owned, a place to host your PowerShell modules. Every time I release a new PowerShell module, it's readily available for me or anyone with a single command Install-Module. No need to host it yourself, no need to prepare anything - plug & play. Additionally, if your PowerShell module has any dependencies, it will download and install them, so it directly works out of the box. But what if you can't use PowerShellGallery? What if you don't want to use Install-Module on 100 computers, but you prefer to do it in a more controlled way? What if your servers do not have internet connectivity?

Comparing two or more objects visually in PowerShell (cross-platform)

For the last few weeks I'm working on a small project, that should be released within next few weeks (it is open source so don't worry - you'll get to play with it). This project requires me to compare two or more objects and tell if those are equal and if those aren't to what degree. Of course, PowerShell offers built-in functionality via Compare-Object command. It's mighty but it leaves comparing differences, different properties to you. While there are probably other solutions that help users compare objects, I haven't found anything that would meet my requirements. After I've written Compare-MultipleObjects function, I thought it could be interesting to implement visual comparison - you know human-readable - and I had the perfect place to apply it.

Formatting and minifying resources (HTML, CSS, JavaScript) with PowerShell

When you work with HTML, CSS, and JavaScript, you often meet three versions on how those are stored in files - minified, formatted, somewhere in the middle (usually a total mess). I have all three versions in my PSWriteHTML module. Some are minified 3rd party resources, some are generated by my PowerShell commands (and are a total mess when it comes to formatting), and finally, some are formatted resources by using built-in VSCode features. In whatever form they are, they generally have no impact on how browsers display them. Browsers will read them in any kind and not care for how they look.

Getting Active Directory Last Backup Time using PowerShell

I shouldn't be telling you that, but Active Directory Backup is an essential part of your Active Directory setup. When a backup of Active Directory happens, AD is aware of it. Following PowerShell solution allows you to get Active Directory Last Backup Time for the whole forest or by domain.

Working with HTML in PowerShell just got better

Last few weeks, I've been working on making creating HTML based Dashboards, Reports, and Emails better. PSWriteHTML already allows fancy looking reports or emails without much effort, but this release makes it even more helpful. I will be mixing three PowerShell modules in this blost post - PSWriteHTML (responsible for creating HTML/CSS/JS code), Emailimo (simplifies creating emails based on PSWriteHTML) and Dashimo (simple dashboard building). If you've never heard of those modules before I encourage you to start from earlier blogs about them to understand the concepts before you dive into this one.  Hopefully, those will give you some ideas that will match what you will learn today.

Testing LDAP and LDAPS connectivity with PowerShell

One of the common ways to connect to Active Directory is thru LDAP protocol. There are a lot of applications that talk to AD via LDAP. By default Active Directory has LDAP enabled but that's a bit insecure in today's world. That's where LDAPS comes in. It's not easy to set up, but when you get it done, it works. The problem I had recently is that while setting up LDAPS on DC's I only did this on some of the DC's, and not all of them as I should.

Instant Replication between Active Directory sites with PowerShell

In Active Directory when you change something, it's replicated to other Domain Controllers regularly. It's a standard procedure that happens automatically in the background for you. It's a handy feature because you can have multiple DC's all over the world and have your users data in sync. You can change almost anything on DC nearest to you and be sure it will be the same value all over the place. But is it always the same? Well, it should be unless it isn't. Today I was given a new migration from  Exchange to Office 365. I started with ADConnect installation and wanted to make sure that UserPrincipalNames have all UPNSuffixes in place.

Executing hidden or private functions from PowerShell Modules

When you write PowerShell modules, there's a high chance you will have conflicts with either existing system commands (you should avoid that) or with someone else's modules. There are also times when someone wants to use a private function from a module that only exports essential functions. Here's a couple of ways how to deal with those scenarios.

Using Lansweeper with PowerShell to your advantage

I'm on a tight deadline for one of the chapters for PowerShell Conference Book vol. 2. That means my brain wants me to do a lot of different things but writing that chapter. I've decided to write this simple PowerShell command that allows me to use Lansweeper in PowerShell. If you never heard of Lansweeper, it's a great inventory tool that can scan Windows, Linux, Network, Printers, and other types of assets gathering it all in SQL Database. Usually, you would use their friendly, fast interface to access data it stores because it offers a lot of flexibility, export options, and many many features.

Getting Bitlocker and LAPS summary report with PowerShell

Having Bitlocker and LAPS in modern Active Directory is a must. But just because you enable GPO and have a process that should say Bitlocker and LAPS are enabled doesn't mean much. Now and then you should verify things yourself. One of the Facebook users on PowerShell group just had this idea of exporting Bitlocker keys and then giving that list to his colleagues for manual verification. He wanted to do it half PowerShell and half manually. While the idea was great, why not take full advantage of PowerShell and have a helpful report with all the necessary information?

Sending HTML emails with PowerShell and zero HTML knowledge required

I saw this article by Altaro tweeted Building PowerShell Tools for MSPs: HTML Tables for Reporting, and it describes how you can create HTML emails with just a few lines of code. Luke created that article in 2018 (tweets from the archive I guess), but I just saw it now so thought I would make a slight comparison. In 2018 I would probably go the same way as shown by Luke Orellana, who takes a simple example of querying WMI to get disk drive sizes and send them over, formatted via Email.

All your HTML Tables are belong to us

Last few days, I've fulfilled my little dream related to building HTML tables. You know I've been using HTML based scripts for a long while for Microsoft Exchange from multiple people like Steve Goodman or Paul Cunningham (and others) and when I was going thru their PowerShell building code on how they create an HTML table with multi-row titles I thought Those guys are crazy. The effort to build an HTML table for a report for a person who has no clue how to do it is not something one can easily digest and understand. Sure I've learned how to build HTML tables at some point, but there was one final piece that I was missing - multi-row headers. If you don't know what I mean, and how they look like the below image from Steve's Goodman script should give you a hint.

Fixing Active Directory PasswordNotRequired with PowerShell

There was I, deploying PSPasswordExpiryNotifications for one of my Clients when I started getting complaints that some users are not getting their Password Expiry Notifications. Well, that's a new one. I've tested this script multiple times, and it worked just fine. So I dive into the details of my script to see what I did in there (I don't even remember anymore - it just works) to find out this little line:

Export-CliXML and Import-CliXML serialization woes

I've been working today trying to deliver to one of my Clients Active Directory documentation. To my surprise, something that worked fine for a very long time has started to provide weird results. So, after spending about 8 hours taking apart a few of my PowerShell modules trying to find out what is wrong finally, I've found it: Export-CliXML / Import-CliXML. Those two commands are great. I've used them multiple times with great success (or so I thought).

Dashimo (PSWriteHTML) – Charting, Icons and few other changes

A few months ago when I first released Dashimo, I've promised that Charts will come. Unfortunately, time passed by, and there were no Charts in sight. It's not that I didn't want to deliver, I just wasn't sure on the way I want to allow charts building. Today after playing with the idea for a while I've decided to release essential support for diagrams, with a couple of other fixes. Some of that stuff is already there for longer while I just never announced it. There are probably a lot of other hidden gems you may find if you explore PSWriteHTML or Dashimo.

Getting Windows 10 build version from Active Directory

Today I saw an article on how to get Windows Version Report from Active Directory and thought that this is a cool idea. Something handy for migration scenarios or information on how up to date is your infrastructure. Since there are many ways to do the same thing I decided to tackle this myself and further include it into PSWinDocumentation.AD project. By default Active Directory stores Operating System and Operating System Version but it doesn't really show versions one may expect.

How I didn't know how powerful and fast hashtables are

I've been using PowerShell for a long while now using Hashtables, OrderedDictionary, and other types of data types in PowerShell, but I never paid attention to how powerful those are. And I don't mean your general knowledge about hashtables that is already covered by Kevin Marquette in his article Everything you wanted to know about Hashtables or my article PowerShell – Few tricks about HashTables and Arrays I wish I knew when I started.

What do we say to writing Active Directory documentation?

It's no secret that nobody likes creating documentation. I don't like it, and you don't like it, even documentation lovers don't like it. But while you can live without documentation, you really shouldn't. And I am not talking here only about documentation that is only useful in the onboarding process of new employees or documentation concerning introducing someone to some concepts to get them easily start. I'm talking about documentation for your live environment where you know what you have, how you have set it up, but is still the same after one week, one month, or one year? Usually, not so much. And one of the worst mistakes admin can do is assume that his environment doesn't change, things are as they were when they were set up.

The only PowerShell Command you will ever need to find out who did what in Active Directory

While the title of this blog may be a bit exaggeration, the command I'm trying to show here does it's best to deliver on the promise. What you're about to witness here is something I've worked on for a while now, and it meets my basic needs. If you don't have SIEM product or products that monitor who does what in Active Directory this command makes it very easy, even for people who don't have much experience in reading Event Logs. If you'd like to learn about working with Windows Event Logs here's a great article I wrote recently - PowerShell - Everything you wanted to know about Event Logs and then some.

Does having Format-Table or Format-List in the middle of the pipeline makes sense?

Recently there was this discussion on PowerShell Group on Facebook about issue posted by one user. While the subject doesn't matter for this post, few people commented on the idea that he was using Format-Table in the middle of the pipeline to do something. They all said Format-Table should be used as last in the pipeline. Otherwise, you would get the wrong output. But should it? Well, it depends!

Preparing Azure App Registrations permissions for Office 365 Service Health

As you may have seen in my other post, there's a simple, PowerShell way to get Office 365 Health Service data for you to use any way you like it. But before you can use that, you need to register granular permissions on your Office  365 tenant so that that data is provided to you. Here's a step by step way to do it.

PowerShell way to get all information about Office 365 Service Health

Office 365 is an excellent cloud service. But like any service, there's some infrastructure behind it that has to be cared for. Since this is Cloud, Microsoft does this for you. But any problems Microsoft has to have some impact on your end users. And you may want to have that visibility for your users. Microsoft provides this to Admins when they login to the portal, but while useful you may want to use that data in other ways than those planned by Microsoft.

Meet Emailimo – New way to send pretty emails with PowerShell

When reading this blog post, you may be thinking that there's nothing new one can add to emailing with PowerShell as there were tons of articles in recent years covering this subject pretty good. It's all known, and people have used it since the early days of PowerShell. You can even send an email with just one line using Send-MailMessage. Now, this post is not about that. This post is about sending HTML based emails. You see when you want to send an email that is just text based that's pretty trivial. Things get complicated when you want your emails to have some colors, some tables, some links or some lists. This is where you have to involve HTML and CSS. Since I've been working with PowerShell for a while now, I've seen my share of scripts/modules or blog posts that cover this but one thing that usually hit me - it was sometimes tough to understand what is happening, what the author is doing, and what happens if I change this or that. While I've seen people dismissing programmers doing HTML / CSS or JavaScript for not being real programmers, I disagree entirely. You have to know what you're doing if you want your stuff to look good. I've spent days or even weeks playing with HTML/CSS/JS, and I must admit half of what I do I don't even understand until I see the output. So before you go and tell people that HTML/CSS is easy, think again.

Out-HtmlView – HTML alternative to Out-GridView

One of the most comfortable output's in PowerShell to work and analyze data is Out-GridView. It's handy as you can search, sort and have things done quicker than trying to do things in the console. However it's currently not available in PowerShell Core (PowerShell 6+), and when it is available in PowerShell 7, it will NOT be cross-platform.  Since I had released Dashimo a few days ago, I thought it was trivial to make a simple command out of it that could solve this problem.

Dashimo – Easy Table Conditional Formatting and more

Dashimo ultimate goal is to be as easy to use as possible. With the introduction of it a few days ago I made a promise to myself that I want to keep it as simple to use as possible. If you don't know what Dashimo is, have a read here - Meet Dashimo. When I posted it on Reddit few people had some ideas and feature request that would make it a bit nicer, and when I heard about I agreed. So today, after a couple of days I have a few updates. I also noticed that my examples might have been too hard to use and understand for beginners and people not having a lot of touch with Active Directory. This time all code you can find below will use Get-Process as a way to show you that you can use any output that comes as a Table.

Meet Dashimo – PowerShell Generated Dashboard

Today I wanted to introduce a little product that I've created in the last few weeks called Dashimo. It doesn't cover everything I wanted from it (feature wise), but it already can be used in production. Therefore, I thought it would be a good idea to get some feedback on whether I should spend some more time on it or throw it in the dumpster. Dashimo joins it's older brother Statusimo of PowerShell modules allowing an easy way to build HTML output. If it will feel familiar, it's because it was inspired with Bradley Wyatt PowerShell script he did. It gave me the idea of how I would like to build something similar but in a bit different way then he did, with much more flexibility. Still, if it wasn't for him, the idea wouldn't be there, therefore you should send him your thanks.

Backing up Bitlocker Keys and LAPS passwords from Active Directory

Having a modern, secure infrastructure in 2019 is a requirement. You should implement BitLocker to make sure that in the event of stolen laptop data is not readily extractable and implementing LAPS is a must in a fast changing IT world. But I'm not here to convince you to those two security features. I'm here to show you an easy way to backup LAPS and BitLocker. While having everything stored in Active Directory is excellent, things can get complicated when you don't have access to your Active Directory, or you restore an older version of it. You see, LAPS, for example, keeps only last Administrator password. This is great and all but what happens if you restore the machine from backup from 6 months back? Your password has already changed multiple times. During our testing of DR scenarios, we wanted to access the computer via their local Administrator credentials and we just couldn't because that password was already gone.

Creating Visual Indicators for spoofed / external emails with PowerShell

I've been managing mail service for users for a lot of years now. I don't do it daily but I've spent my fair share of time analyzing spam emails. Mail vendors are doing what they can fighting spam, but it's not easy. Each month, each year spam is getting more sophisticated. Spam emails either look like a legit email, or worse someone is targeting your company trying to get them to transfer money into a wrong account. While most of those end up in spam, there are those that come thru. It's even worse if the company you work with has not implemented SPF or their SPF is configured to soft fail which can't be treated as spam.

Hosting your VM's in Azure Cloud is excellent. You have all those features, professionally managed and virtually limitless. I don't want to take your time to sell you Azure Services but to share a solution to one of the things I had to solve in Azure and sooner or later you may end up with on. During the test restore for Active Directory and multiple other machines which were much older (or newer) then Active Directory Domain Controller that was restored it turned out one can't log in to most of the devices. First of all your domain password is already changed, but that can quickly be addressed. Your second and more significant problem is Network Level Authentication (NLA), and your 3rd problem is broken trust relationship.

I've been testing Disaster Recovery scenario restoring Active Directory. One of the servers was restored, and it worked for a moment after restore. If you can regain your Primary DC, it's best to do so. If you can't, a standard thing to do during DR is to move all FSMO roles to the restored server so that it can become a master server.

Using PowerShell to fix Ubiquiti Unifi requirement for MongoDB 3.6 on Ubuntu 18

I've been using Ubiquiti Unifi for some years now, for both home and work usage. It's great hardware at a great price, and the best thing for a software maniac like me is that it's continuously updated. Some time ago I upgraded Ubuntu to 18.04, and things went a bit sideways. You see Unifi started to add to their DEB packages that Mongo 3.6 is not supported and therefore blocking any installation. The idea is, it works perfectly fine on MongoDB 3.6 but migration between 3.4 to 3.6 is just not straightforward. Long story short when I upgraded Ubuntu I was suddenly greeted with not working Unifi.  I've fixed that, and blogged about it how you can do so using manual steps - Ubuntu 18.04 – Fixing Unifi .deb package to run with 3.6 MongoDB. The thing is with each new version out I have to do multiple steps to fix every single package from Unifi (you see where I'm going right?). While a few years ago I would be stuck to use bash or some other workaround which would be a pain for me, this is 2019, and PowerShell Core works excellent on Linux systems! I know that installing PowerShell Core for hardcore Linux fans may not be as fun as it is for me, but you do get a lot of benefits from it.

Meet Statusimo – PowerShell generated Status Page

A few weeks ago, Mateusz Czerniawski, mentioned that he wants to build a Status Page for his company services. While I haven't needed for myself, it seems like an excellent idea to try and create one in PowerShell. Since I've been working on PSWriteHTML for a while, it wasn't that far fetched idea. While PSWriteHTML has a long way to go, to be in a state I want it to be, after a few days I had a prototype that didn't require much work to generate. If you're wondering what Status Page is it's a little summary page for your users to check what is the status of services they use. It has been popular in the last few years and is offered by many services (Twitter, GitHub, Office 365 - they all have it). Companies are selling it as a service as well where you can host your status page for your users. This one is free.

If you feel this title is very familiar to you it's because I actually have stolen the title from Kevin Marquette. I'm in awe of his posts that take you thru topic from beginning till the end. No splitting, no hiding anything, everything on a plate, in a single post. That's why I've decided to write a post that will take you on a trip on how to work with Event Logs, something that is an internal part of Windows Administration.

PowerShell – Few tricks about HashTables and Arrays I wish I knew when I started

I've been working with PowerShell for a while now and like with most things I do I've learned it by doing and not by reading. I had a job to do, and since I don't like doing things over and over, I thought it's time to learn and do it in PowerShell. Problem with that approach is that you take bits and pieces from PowerShell scripts online that sometimes do the job but not necessarily pay attention to details. And it's fine. I've learned a lot from reading someone else's work, and I learn something new every day. Hopefully, it will be useful to you to some extent.

How to find different server types in Active Directory with PowerShell

Working as a freelancer is a great thing if you can handle it. Each day, each week something new happens and a new problem shows up on my doorstep. It also means it's almost never boring at your job and you get to play with new stuff. But there's one drawback to this. You're often thrown at the problem, told to fix it but often that's about as much information as you get. It wasn't very different today. I was told to switch Office 365 from ADFS to Password Synchronization. While reasons for this are not really important, the important question here is what is the name of AD Connect server that's responsible for this configuration?

A short story on PowerShell HashTables that beat me hard

Today's story happened a few days back to me, and I think many people may not even know about some object behaviors in PowerShell (just like me). I know some of you may think this is basic PowerShell knowledge but even thou I've written a lot of different PowerShell modules I kind of skipped basics. That means I often find myself struggling with something that's obvious if you've done your due diligence before starting to work with the code. But that's typical me, playing with complicated stuff, failing at simple things.

Working with Office 365 is my bread and butter in the last few months. I'm a System Architect and I am dropped in multiple projects, both new and old, to fix certain aspect and get out before anyone sees me. One of the common tasks I get is to provide some data about users stored in Office 365.

Active Directory – How to track down why and where the user account was locked out

I've been working with Windows Events for a while now. One of the things I did to help me diagnose problems and reporting on Windows Events was to write PSEventViewer to help to parse the logs and write PSWinReporting to help monitor (with use of PSEventViewer) Domain Controllers for events that happen across the domain. It's handy and I, get those excellent daily reports of what happened while I was gone.

How to change your own expired password when you can't login to RDP

I must admit that it was a bit embarrassing to see my Administrator password expired when I tried to log in as Domain Admin to Domain Controller. I got this little message saying This user account's password has expired. The password must change to logon. Please update the password or contact your system administrator or technical support.

Windows 2019 – Windows License Expired

Windows Server 2019 is out now for a couple of months now, and some of you may be interested in playing with it. When you first install it, you can test it for 180 days (so-called Grace Period) after which you need to activate it with a proper production license.

PowerShell modules I worked on in 2018

We're a few days in 2019, and from a time perspective, I can say I had a busy 2018. I must say I've never expected that but in 2018 I've created or worked on 24 PowerShell modules. Some were simpler ones, some were a bit more advanced, and some will be retired in 2019 because their features will be moved to other modules. In PowerShellGallery alone those were downloaded over 15000 times (I must admit that some of those are surely automated tests - "Hello Pester" that I've learned in 2018. It's a nice number thou, and something I'm kind of proud of myself. After all, before 2018 I've not created a single PowerShell module before. Sure, I've created a bunch of scripts, hardcoded, that did the task that I had to solve. But I've never before built something, that could be installed by one little command Install-Module (something I've learned in 2018 as well) and executed by anyone, anywhere. I know the title says Sixteen PowerShell Modules but some modules are just too simple to give them anything else than a small mention.

Active Directory – Move-AD Directory Server Operation Master Role: Access is denied

When working with Active Directory one of the common tasks is to move FSMO roles between servers. Well, maybe not that common but it happens from time to time where you have to move all or just some of the FSMO roles. For that purposes, there is single PowerShell command Move-ADDirectoryServerOperationalMasterRole. Sure you can do this via GUI but if there's one command available to fix it all why bother? To make the move one has to be a Domain Admin, Enterprise Admin and Schema Admin. Everything was going smoothly for some roles but wasn't working for others.

A command with name is already available on this system. This module may override the existing commands.

Another day, another issue one may say. Today I wanted to install one of my modules to a new server and was greeted with a well-known message (it may seem on first look): A command with name '' is already available on this system. This module 'PSEventViewer' may override the existing commands. If you still want to install this module 'PSEventViewer', use -AllowClobber parameter.

Windows 2019 – How to add language pack?

Today I've been setting up a new server on Windows 2019. By default, I install Windows with English version even if Client works in their language such as German, Polish or Swedish. While some people install Windows in a language they desire to work with, years of experience taught me that installing English and then adding Language Pack is the best way to go. All errors, windows events, and general troubleshooting is much easier if those are in the native English language. Each version of Windows made it easier to install the language pack and have that up and running in no time. In Windows 2019 it's even more comfortable... or is it?

Import-Module: This script contains malicious content and has been blocked by your antivirus software.

I've been working today on a little project when suddenly my modules stopped working. It was weird because I have not touched anything that could cause it. A message was a bit cryptic mentioning that my PSWriteColor module is required but not available. I've decided to try and load PSWriteColor manually using Import-Module command.

Azure Agent – Where did my space go?

Recently I had a weird case where one of our Azure servers was starting losing space pretty quickly making Pulseway go nuts. As you can assume from the title of this post the cause for this is Azure Agent itself. But before I actually knew that I had to do some digging as it's not that obvious because Windows Explorer isn't showing anything worth checking.

Outlook – The primary account cannot be removed unless it is the only account in the profile

Last few months I'm responsible for the migration of Office 365 to Office 365. While doing so, we came into a situation where users have their old mailbox as Primary Account and new Mailbox as their secondary account. This is a quite common scenario that people are running into and something that is expected. Usually, my recommendation is: Please create a new profile for user and topic is closed. It's also quite easy to achieve this in an automated way where you delete all profiles and Outlook just goes with autodiscovery adding new account as required. That's how I have always done this till now. My Client has gone thru setting up 1000+ users with their second account in Outlook and deleting a whole profile, recreating would cause lots of downloading of emails from Office 365 that my Client wanted to avoid.

PowerShell – Working with Format-Table in Verbose, Debug, Output Streams

As you may know, PowerShell has multiple streams. Write-Output, Write-Error, Write-Warning, Write-Verbose, Write-Debug, and Write-Information. It also has Write-Host which until PowerShell 5 was a bit special. Since PowerShell 5.1 it's a wrapper over Write-Information, so it doesn't kill puppies anymore. While I could spend the next five pages trying to give my best and describe those streams, there are already many articles describing them in detail. Please check the following link if you need that information.

PowerShell – Single PSM1 file versus multi-file modules

I've been working with PowerShell Modules for a while now, and most of my knowledge about them came from Warren F (psCookieMonster) blog about Building a PowerShell Module. It is a handy piece of information and recommended read for anyone starting up writing PowerShell Modules. He introduces an idea where a module is stored in multiple folders Private, Public, Bin, Lib and so on and having YourModule.psm1 as a wrapper for functions, binaries in those folders, where each function is stored in its file. It's an excellent concept, and I use it every day. It allows me to jump into a file quickly I want to find and fundamentally easier for development, especially in teams.

Microsoft Exchange – 420 4.2.0 Recipient deferred because there is no Mdb

Last few weeks I'm responsible for migrating from Office 365 to Office 365. Part of this migration process is to set up new Exchange 2016 server that will work as relay instead of using IIS server. I've setup hybrid, added accepted domains, prepared connectors, but there's one thing missing. Any time an email is sent via relay to a user that exists on Office 365 and at the same time exists in Active Directory email never gets there.

Bittitan MigrationWiz – Users getting undergoing maintenance message

MigrationWiz from Bittitan is one of the best tools on the market allowing for migration of user mailboxes. Whether it's a google account, exchange account or IMAP, it will help you out. Last few months I'm part of migration project that is using Bittitan at its core. One of the signature features of this tool is the ability to migrate mailboxes from Office 365 tenant to Office 365 tenant. This is not something that every application can do. Another feature (and something I want to address today) is the ability to ask users for their logins and password to migrate their data from one tenant to another tenant. While in general, you shouldn't do that and you should use migration accounts with proper permissions sometimes you have no other choice.

Azure AD Connect – Synchronizing MAIL field with UserPrincipalName in Azure

Azure AD Connect is an application responsible for synchronizing Active Directory with Azure AD allowing for a natural population of users, groups, and devices in Office 365. While for most companies standard setup is very easy and most of the time touch-free, there are companies which require greater customization. During installation of AD Connector, you choose what should be used for Azure AD Username from your AD. UserPrincipalName field is an obvious choice for this and also proposed by default for that purpose. This field is utilized further by your users to log in to your Exchange, SharePoint, Teams and so on.

PSWinDocumentation – Audit Active Directory Passwords

If you're paying attention to what's happening around the world now you probably know Have I Been Pwned service by now. You probably know that it has huge lists of hashes of passwords that leaked out over the years from different services (LinkedIn, Adobe, and so on). This means those passwords are now in possession of good guys, but also bad guys. With Active Directory being often a central place to store your password that allows you to access your Office 365 account, ADFS, Microsoft Exchange it's important that your AD passwords is both secure and safe. Bad guys may want to try and access your email accounts or other data that's available online. And having a list of passwords you or other people may have used before doesn't help you in protecting your own data.

I got help from Mateusz Niemczyk who is a certified AWS engineer working for Euvic with me on some projects. If you've not yet guessed where I got him involved from the introduction - yes we're adding basic AWS data support to PSWinDocumentation. But that's not all...
