Windows 7 SOE – Reset Computer Groups Script

The application deployment setup in SCCM 2007 means you have to tend towards application deployment based on a user’s computer rather than the user’s account. One method of doing this is to have the computer in security groups that relate to collections to deploy the applications. For example, you may have a security group called “SCCM_Viso2010” to deploy Visio 2010. Where this becomes an issue is when you reimage the machine, you need a method of resetting the machine back to a default state so it doesn’t recieve those extra apps again. The script below was designed to achieve this.

add-pssnapin quest.activeroles.admanagement

write-host "Getting SID, GUID and DN for $env:computername"
$strComputer = get-qadcomputer $env:computername | select sid,guid,dn

write-host "Getting groups for $env:computername"
$strComputerGroups = get-qadmemberof $strComputer.SID

foreach ($obj in $strComputerGroups) {
if ($obj.Name -eq "Domain Computers")
{
write-host "This is the default group, do nothing"
}
else
{
write-host "The group $obj is a non-standard group"
remove-qadgroupmember -identity $obj -member $strComputer.SID
}
}

# Removing Quest AD snapin
remove-pssnapin quest.activeroles.admanagement

The behaviour of the script is to remove any group that isn’t the default group of “Domain Computers”. Like the OU move script, it utilises the Quest AD cmdlets.
