I have setup a new clientpc on my SBS2003 server. On the client I then ran the ConnectComputer-wizard. After that I installed the assigned client applications.
After a reboot however the client PC is not registered on my server anymore.
When I try to login to the domain from that client I get a message about trust relationship that blocks my access. However when I run the connectcomputerwizard again I get a message that this computer is already part of a domain.
Also, when logged in as a local Administrator I tried to add a new local users. This failed: the 'User could not be added, because no such user existed' or words to that effect.
