So in XP and Vista, I use NETDOM after imaging to join the computer to the domain and then rename the computer (and its AD account) if necessary. I noticed that Win7 didn't work with the old copy of NETDOM that I used for XP and Vista, but I see that a copy gets installed when you install the RSAT (Remote Server Administration Tools). However, if you take the RSAT copy and move it to another machine that does not have RSAT installed, it doesn't work - when you launch it, it just exits without any output. (As a matter of fact, even if you move it to a different machine that does have RSAT installed, it still doesn't work!) I would use the PowerShell cmdlet Add-Computer, but I need to rename the computer in the same operation without restarting, which I was able to do under XP and Vista with NETDOM (NETDOM ADD and then NETDOM RENAMECOMPUTER). Any ideas, or has anyone else experienced this issue? If you add your machines to the domain post-imaging, how are you doing it?
