I do not get that message, but I do think that the problem might be related
to DNS. The Samba box can see all of the DNS records pertaining to the
Windows DC, but none of the records that the Samba DC needs to add to
DNS are being added. So the Windows DC does not see any records pertaining
to the Samba DC. I just found out that automatically adding these records
to a Windows 2000 DC is not supported (see my email with subjects 'Dns
updates not working' and 'How stable are DNS records'). I may try to add
them by hand on the Windows 2000 DC.

Unfortunately we do not have any newer server class Windows machines
available. We looked into upgrading the server 2000 machine to a server
2003 machine, but we have some worries about that. We are running an
important application (Syteline) on it that is not under maintainance
and we do not know if will work correctly on Windows server 2003. And
when I looked into buying Windows server 2003, the licensing drove me
Applied Dynamics Intl.
