[Samba] Can't find Domain Master Browser

[Guillermo Gomez]

Hi

I have a couple of Samba servers, one is set as a PDC.
The non-PDC Samba is becoming the local master browser but it can't find 
the Domain Master Browser which is the other Samba server.

My (tail) of log.nmbd is:

   Got SIGTERM: going down...
[2002/03/14 16:27:55, 0] nmbd/nmbd_become_lmb.c:become_local_master_stage2(405)
  *****
  
  Samba name server NEOTIX is now a local master browser for workgroup NEOTECHGW on subnet 10.161.170.116
  
  *****
[2002/03/14 16:28:16, 0] nmbd/nmbd_browsesync.c:find_domain_master_name_query_fail(360)
  find_domain_master_name_query_fail:
  Unable to find the Domain Master Browser name NEOTECHGW<1b> for the workgroup NEOTECHGW.
  Unable to sync browse lists in this workgroup.

Someone knows what can be wrong ? I'm using RH7.2.

Regards
Guillermo
