I work as an NT Systems Administrator at a university. We're currently having problems with people locking NT and 2000 machines and leaving them locked for long periods of time. It's annoying to constantly have to go around to all of the machines and unlock them. I'm wondering if there is a way to either make it impossible for users to lock a computer (but only for certain users, ie administrators could still lock machines) or to set a time limit for locking a machine (ie the user would be automatically logged off after a certain amount of time). In searching for a way to do this, I've run across NOLOCKWS. This just disables the lock workstation button for all users. However, this isn't exactly what I'm looking for (I'd like administrators to be able to lock workstations), and it doesn't work in 2000 (I've tried it). I'm fairly certain that what I'm looking for can't be done with policies or registry settings. Does anybody have any suggestions?
