This article contains links for setting Group Policies for Windows 2000 servers.
The Basic Problem
When installing updates - controls may not register on workstations without
administrator rights.
Once a user logs on, the group
policy can automatically install new software, updates etc. This works with
Windows 2000 and Windows 2003 servers and Windows 2000 & XP clients.
