I just went through all this so here are the resource I
used...
There is a web cast at the following url from microsoft:
http://support.microsoft.com/servicedesks/Webcasts/WC020901/wcblurb020901.asp?LN=EN-US&SD=tech&FR=0&qry=group%20policy&rnk=1&src=DHCS_MSPSS_tech_SRCH&SPR=WIN2000
IF the link doen't work go to technet and knowleedge base on Microsofts site and type in "group policy"
Also, active directory needs to be installed which means dns needs to be setup the wizzard usaully takes care of the server side but you need to set up the clients. Thst will depend on your network. Then I would refer to the following Knowledge base articles listed below.
I also used a book Titled "Windows 2000 Server Visually" That help out interms of getting started. I can't remember the author. Another good one was SAMS "Teach yourself 2000 server in 21 days." I spent a whole weekend on setting this up and some of the stuff doesn't work by Microsofts own admission. One other thing. All the clients should be 2000 workstations for this to work best. You can do NT style policies for those workstations. I foget the comamnd to bring that up. I can look it up if you need it. I am not reaslly sure how and if it will work with 98, ME and XP home...
BTW have a bnackup of your system before installing the active directory it can be undone but I found it quirky and had to reinstall the OS (Ghost is the best bet)
