No. Well, not yet.

No. Both the new file server and the PDC have been online at the same time and 
working. I could log into the domain and even map the shares on the new file 
server. This was before they purchased the new switch. I plugged the new file 
server into a jack on one of the three older switches that had an off computer 
at the other end of the jack. The PDC is the wins server and the new server is 
set to use the PDC wins server.

No to both questions. The config file for the new file server is from scratch 
(well, modified the sample config file). The PDC is samba 3.0.something, while 
the new file server is samba 3.5.something. I've been on their case about 
upgrading the PDC, but it's so far fallen on deaf ears.

Fail to learn history-repeat it.
Fail to learn rights-lose them.
Learn both-get screwed by previous two groups.
