Documenting with PowerShell Chapter 6: Documenting Active Directory groups

This will be the last post in the documenting with PowerShell series for a short while. I’ve enjoyed the series thoroughly but there are so many choices to blog about and I want to take a short break to be able to prepare the next series with all the requests I’ve been getting.

This time we will get al the current active directory groups, list all users in these groups, and even attach the contact as a tagged resource in IT-Glue. This way, you can look up a specific contact and find that exactly in which groups they’ve been added. It’s also pretty cool to combine this script with the previous blog found here.

And that’s it. This will help you document all your security and distribution groups. You’ll even see them in the contact sidebar, so you have a quick overview what user is in what groups.

And that’s it! as always, Happy PowerShelling.

The return of CyberDrain CTF

CyberDrain CTF returns! (and so do I!)

It’s been since september that I actually picked up a digital pen equivalent and wrote anything down. This was due to me being busy with life but also my side projects like CIPP. I’m trying to get back into the game of scripting and blogging about these scripts. There’s still so much to automate and so little time, right? ;)

Monitoring with PowerShell: Monitoring Acronis Backups

Intro

This is a monitoring script requested via Reddit, One of the reddit r/msp users wondered how they can monitor Acronis a little bit easier. I jumped on this because it happened pretty much at the same time that I was asked to speak at the Acronis CyberSummit so it kinda made sense to script this so I have something to demonstrate at my session there.

Monitoring with PowerShell: Monitoring VSS Snapshots

Intro

Wow! It’s been a while since I’ve blogged. I’ve just been so swamped with CIPP that I’ve just let the blogging go entirely. It’s a shame because I think out of all my hobbies it’s one I enjoy the most. It’s always nice helping others achieve their scripting target. I even got a couple of LinkedIn questions asking if I was done with blogging but I’m not. Writing always gives me some more piece of mind so I’ll try to catch up again. I know I’ve said that before but this time I’ll follow through. I’m sitting down right now and scheduling the release of 5 blogs in one go. No more whining and no more waiting.
