That's my point, I guess.  If you know the NTdomain name then you know the
PDC's name.  It should answer to <NTDOMAIN>#1B (as DMB) and also to
<NTDOMAIN>#1C (a group name, but the PDC is always the first IP in the
Name Query Response from the WINS server).

In any case, I don't see why a Node Status Query would be needed, and even 
if it is used I don't see why the unexpected.tdb would be needed since NT 
responds to the correct port.
