If you've ever worked with NIS on *nix then it's the same idea but different implementations. Hope I've given you somewhere to start anyways.

WinXP does work in a win2000 Active Directory and you do not need Advanced Server to set up a domain, Win2000 Server will do!

As far as the question asked goes, thehorse13 solution should work.
