[ActiveDir] Assign User rights overs computers with AD

[Alberto Oviedo]

Hello. My name is Alberto, I'm from Nicaragua

In our company the support team has granted every user administrator rights over their workstation, We recently migrated to Windows 2003 AD and I want to revoke the privileges tha users have on their computers. Can I do this through AD?   It's around 300 users and I don't want to visit every single one of them.

Thanks for your help.
