samba - Jul 2006 - workgroup and domain

Hello for all , 

I am new in this list and my English is not good, but I go to try to explain
what it happens with me with logs.
I have some problem with my PDC Controler. Look errors in the log.nmbd

[2006/07/04 09:14:32, 4] nmbd/nmbd_workgroupdb.c:dump_workgroups(284)
  dump_workgroups()
   dump workgroup on subnet      172.16.2.2: netmask=  255.255.255.0:
        PIRA-RAICOM(1) current master browser = DC-PIRA
                DC-PIRA 400c9b0b (dc-pira PDC)
                DESKFURLAN 40011003 ()
                RECEPCAO 40011203 ()

                DC-PIRA 40099b0b (dc-pira PDC)


I run samba 3.0.22-1 on debian sarge.
Somebody knows that if it deals with this error? Because in he appears in my
network neighbor workgroup pira-dc (name of PDC SERVER )  and my network domain 
pira-raicom.

Thanks for the attention
