How much data can the comment field in a Group Policy hold?

There are two places that you can leave comments in group policy. The first place is in the root of the GPO. Right click the GPO in the Group Policy Management Editor and select Properties.

Then select the Comment tab.

Also, if you open an individual GPO property, you can see a comment field.

The question is how much information can these fields hold? I field up one of these fields with as much text as I could. I then copied that data into a text file called Data.txt

I then opened a PowerShell session and executed the command:

(Get-Content Data.txt).Length

The answer is 4095 characters

How to run GPResult on a remote client with PowerShell

In the past, to run the GPResult command, you would need to either physically visit this client, have the user do it, or use and RDP connection. In all cases, this will disrupt the user. First, you need PowerShell remoting enabled on the target machine. You can do this via Group Policy . Open PowerShell and type this command.

Set up your Environment to utilize Invoke-GPUpdate

I’m sitting in O’Hare enjoying my 3 hour layover as I get ready to teach a Windows 10 class in Fort Wayne. I’m actually prepping for my class in Fort Wayne in a few weeks, 10982 Supporting and Troubleshooting Windows 10. This class is very much like the Windows 7 version that I used to teach so I decided to up the detail quite a bit. In the GPO troubleshootin chapter, I’m including a demonstration on how to use PowerShell’s Invoke-GPUpdate. I needed to make sure the environment is set up for me to be able to utilize this cmdlet. If you read the Notes section on Invoke-GPUpdate’s help file, you will see there are three firwall rules that need to be in place: Remote Scheduled Tasks Management (RPC) Remote Scheduled Tasks Management (RPC-ERMAP) Windows Management Instrumentation (WMI-IN) I decided to create a little PowerShell script to crea...

Where did a User’s Account Get Locked Out?

Updated: May 15, 2015 When this article was originally published, two extra carriage returns were add causing the code to malfunction. The code below is correct. My client for this week’s PowerShell class had a really interesting question. They needed to know where an account is being locked out at. OK, interesting. Apparently users hop around clients and forget to log off, leading to eventual lock out of their accounts. The accounts can be unlocked, but are then relocked after Active Directory replication. This problem is solved in two parts. The first one is to modify the event auditing on the network. The second part is resolved with PowerShell. The first part involves creating a group policy that will encompass your Domain Controllers. In this GPO, make these changes. Expand Computer Configuration \ Policies \ Windows Settings \ Security Settings \ Advanced Audit Policy Configuration \ Audit Policies \ Account Management Double click User Account Management C...
