We have a Netware 6 server running CIFS. It has got the right PDC name
IP address and it appears in the domains WINS server. It has not been
a member of the domain.

However if you try to access the server from a workstation you get a
message "the specified server cannot perform the requested operation"
the server logger screen displays the message "CIFS: Unable to connect

primary domain controller [name]".

What is frustrating is that we had the same problem with the first
installation we did and it resolved it self after a few days. We have
had to do a new installation due to a faulty hard disk.
The problem has reappeared. As yet there is no sign of the problem
resolving itself. Apart from that, we would like to understand what
going on.

Does anybody have any suggestions?.
