I have a 2003 server that is in a domain with a bunch of 2000 servers. When I try to add users to the administrators group from one of the other domains, I click on location and I am unable to see the other domains. I can ping to and from servers on the other domains and can Remote desktop from the 2003 server into a 2000 server on the other domain. All trusts are in place and the other servers on this domain can add the users from the other domains. This is the only 2003 server in this domain.
