Update-Module : Module ‘PowershellGet’ was not installed by using Install-Module, so it cannot be updated.

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.

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.

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.

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.

Everyone now and then, there comes a moment you need to add a user into Administrators group on each computer…

Virus Total is an excellent service. It’s a single place where hundreds of antivirus engines can verify if the file, URL, domain name, or IP Address is trusted or not. Of course, it’s not a silver bullet, but it brings tremendous value, and I often verify files I download before executing. Since I release a lot of new or updated PowerShell modules on a weekly/monthly basis, I thought it would be great to send newly released versions straight to Virus Total so I can have them checked before anyone executes them. I also hope to prevent false positives from some antivirus vendors that may tag my modules as malware because they haven’t seen the DLL or PowerShell module in this form before. I’ve seen it happen to DBATools, so why not try and push my modules before users even use them?

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. In the end, if something goes wrong, the rollback will not be a walk in a park. It will hurt, and it will eat your time. So there was I going thru the usual steps.

I have to admit – executing the same command three times and expecting different results is dumb, but I still do it anyway. Fortunately, after trying three times I usually resort to other methods and try to solve the problem I have. Today while trying to trust PowerShellGallery I was greeted with an error.

When I created ImagePlayground, I thought about how to show its usefulness to the general community. On how to deliver what PowerShell can do. Then I saw on some forum people asking BGInfo to expand and allow running PowerShell scripts so that the data on the BGInfo Wallpaper can be gathered from PowerShell rather than VBS. I thought this was a great idea to create BGInfo using PowerShell without the necessity of using BGInfo at all.

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.

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.
