Find out if you still have any Windows 2000 objects left in your domain
I was recently asked by a friend how to find Windows 2000 computers with PowerShell.
While its very easy to accomplish with ADUC, he needed a script.
Every computer object in Active Directory has an Operating System attribute (simply called “OperatingSystem”).
All you need to do is to use Get-ADComputer cmdlet and provide an expression for its filter parameter.
