[Samba] SAMBA 3.02rc2 ERROR in nmbd command

[Luis Alberto Reyes R.]

we have installed a samba server 3.02rc2  in a redhat linux 9, the first 3
days works fine, but today is not possible to initialize the nmbd command,
it says that exists the following error (all other logs are ok, the samba
server itself is working fine, but it is not possible find the netbios name
int the network):
