Servidor wins

Olá a todos!
Aki esto utilizando o servidor wins para registrar as maquinas windows e
com samba. meu servidores e minhas estações estão registrando blz. so
que tenho um servidor de firewall que estou tentando fazer ele registrar
o nome no servidor wins so que não consigo simplesmente ele não registra
o log fica dando erro. abaixo chegue o log.
Desde ja agradeço:
A configuração do samba deste servidor de firewall esta desta maneira
abaixo:
name resolve order = wins lmhosts bcast

# Windows Internet Name Serving Support Section:
# WINS Support - Tells the NMBD component of Samba to enable it's WINS
Server

wins support = no

# WINS Server - Tells the NMBD components of Samba to be a WINS Client
# Note: Samba can be either a WINS Server, or a WINS Client, but
NOT both

wins server = 192.168.1.10




Aki esta o log gerando quando ele tenta registrar o nome no servidor
wins
