Anyone knows of a script that would power off computers based on the following. If a user is logged on the computer it would not be shutdown All other computers on and not logged in would be powered off at a set time The script would use computer names from a specific OU in order to decide what computers to power off. Basically all computers under a set would be shutdown if no user was logged on and the script would get the list of computer names from AD.
