Win2K GPO Security Rights (Users and Groups)

On a Windows 2000 Domain, using Active Directory.

I know if I want to setup some permissions on a group, I add in a GPO and say stuff like, this group has a quota, or must show login script... etc..

I don't want that kind of stuff, maybe it's somewhere else or maybe I'm missing it.

I want to say stuff like, this group can not create groups but can create users. Or this group can add users to groups, but can not create groups. This group can create groups and users and that's it.  This group can edit only select fields in the user properties window.

I'm pretty sure this is possible, just can't remember how to do it.  If you answer this question, go on over to this link and put a comment up with a link back to here, I'll give you the 50 points from the other one too.
