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

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.

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.

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. You can find out your FSMO holders by using those commands below:

In my earlier blog post, I showed you a way to find duplicate DNS entries using PowerShell, but the focus was on finding duplicate entries based on hostname. But what if you would like to find duplicate entries based on IP Addresses? This was the question I was asked on Reddit, and I thought it was a legitimate request, so today’s focus will be on transposing table output from earlier functions to present data differently. 

Today I had a need to connect to Microsoft Graph and do some tasks on Office 365. 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.

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.

A few days ago, I tried to use Install-Module on the old Windows 2008R2 system that I use for specific tasks.

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.

Hey there! Today, I wanted to introduce you to one of the small but excellent module I’ve created called the O365Synchronizer. This module focuses on synchronizing contacts and users. If you’ve ever been tasked with synchronizing Global Address Lists (GAL) across different Office 365 tenants or just wanted to sync GAL with user mailboxes so they can access contacts directly on their phones, this tool is for you.

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!
