[Samba] winbind problems

[David Schell]

I have a FC4 box acting as the PDC, using samba 3.0.23

The PCs are having trouble joining the domain/logging into the  
domain.   I have traced this back to what I think is a problem with  
winbind knowing the name of the server.

Immediately after a restart of samba, things work for a few minutes  
and I get this:
[root at anserver ~]# wbinfo -N anserver
10.50.4.252     anserver

after a few minutes, things stop working and I get this:
[root at anserver ~]# wbinfo -N anserver
Could not lookup WINS by name anserver

However, it seems to work find for other computers
[root at anserver ~]# wbinfo -N and_lin
10.50.4.3       and_lin
