Actually, netbios id <1B> is not determined by election: this is a netbios
name that is registered with the WINS server. There is no reason for this to
be elected, since the domain master browser / PDC should be a stable,
centrally-administered machine. You must configure an NT server to be a PDC.
When it boots up, it will check to see if domain<1B> is registered with the
wins server. If it's registered, NT spits out an error message and doesn't
become a PDC. If it isn't registered, it registers the name with its own IP.
If Samba has 'domain master = yes' set in smb.conf, it will register
domain<1B> with *its* IP -- /regardless/ of whether or not there's another PDC
on the network already.
Setting 'domain master = no' is enough to fix the problem.
