we added an additional file server (win2k3) to our DSfW domain and
created a few print queues. Now I'm trying to access these from some XP
workstation - which is being denied until I create a corresponding
(local) user on the win2k3 box. After having done so I can logon using
any DSfW domain user.

Any ideas? Do I have to create an additional domain on the print server
and trust it towards the DSfW domain in order to succeed?
