I insert my newly created WKS object into an appropriate OS group. (ie WINXP or WIN2K)

my question (which might have been posted before but my searches can empty)

If I upgrade a workstation from 2K to XP how do I have it become a member of the appropriate OS group? (and removing itself from the old group)

Do I have to unreg then remove it manually from the WIN2k group then reg the workstation? Is there a trick to this? Can this be all done without loging into the wks? (200 wks at a backup site, remote desktop would be a pain)
