I was not in the office, but I did have to shut down all domain computers after a move to have them install windows updates over the long new-year weekend.
So I ended up with a script I picked up on the web, and adjusted it to my needs.
The computers in the network were all named dt[number] (dt for desktop).
When looking at the Active Directory and in the DHCP server I found the desktop number range was from 41 to 99 in my case, so I just made sure a remote shutdown command (run as domain admin) was executed with the correct computer name. I saved this as a .bat file and ran it.
@echo off set /a x=41 :while if %x% lss 100 ( echo shutting down dt0%x% shutdown /m \\dt0%x% /s /t 30 set /a x+=1 goto :while )
Hope this helps you!
Have a great new year,
