[Samba] WINS resolution not working on WINS Server

[Ian Clancy]

Hi Samba Users,
I'm using a typical Samba/LDAP Solution. My PDC is running samba 3.0.14a 
on RHEL4. This is also my acting WINS server.
WINS resolution appears to be working fine for all other PC's on the 
network. It works for my BDC, and Domain member servers and the various 
windows clients on the network. However WINS does not appear to work on 
the PDC itself.

On the pdc i have the following line in nsswitch.conf:

hosts:      files wins dns

The following output from log.nmbd show an unsuccessful wins lookup by 
the PDC (in reverse using tac). I can see CELCZPDC<00> clearly in the 
wins.dat file:

  find_name_on_subnet: on subnet 192.0.2.14 - name CELCZPDC<00> NOT FOUND

Here is a copy of my smb.conf :

# Global parameters

        unix charset = ISO8859-1

        idmap uid = 10000-15000
        idmap gid = 10000-15000
        winbind separator = +
        winbind use default domain = Yes
        winbind trusted domains only = Yes
        printer admin = Administrator


I need wins to work on the PDC to implement trusted domains . Anyone got 
any idea's as to what could be wrong.
regards,
