As a systems administrator sometimes I find myself in a situation where I need to make a registry change across a few computers, or even a few hundred. I was googleing for a while this week trying to figure this out and saw some very complex solutions, but found a few sites to include TechNet that lead me into this much simpler solution: @echo off FOR /f %%F IN (feedme.txt) DO ( REG ADD \\%%F\HKLM\SYSTEM\example\example /v TestValue /t REG_DWORD /d…

A few days ago I wrote up a small post on modifying extension attributes for computer objects in Active Directory. I recently set up a lab with Server 2012 and found that extensionattribute1 is now msDS-cloudExtensionAttribute1, and if you just drop in msDS-cloudExtensionAttribute1 without quotes it has issues… This gave me a small headache, after reading this link I found that simply putting quotes around it, fixed it.

Some of you may find this useful, I ran into this problem where I needed to set the value of an extension attribute on a number of hosts from a list. The following script should take care of that. At the end, it will let you know that the host is finished, it will output an error if one occurs. import-module activedirectory $machines = Get-Content “C:\PATH TO LIST\feedme.txt” foreach($machinename in $machines) { Set-ADComputer $machinename -add @{extensionattribute10 = “VALUE IN THE…
