I have a Windows Server 2008 domain and want to log all Windows 7 and Windows XP users off (since they lock their systems), provide a 15 minute warning before it happens and apply this at the OU level.
I've read lots of posts and several KB articles, but there's many ways to do this and I'm a bit confused. Will someone please provide a step-by-step process I need to follow to facilitate what I need done by Server 2008 GPO only??
Please no links, I need actual steps. Thanks!
