[Samba] samba server not broadcasting

[Margaret Doll]

The following is supposed to give back the ip address of the server, 
but it appears that my server is not broadcasting.  Help!!!

	nmblookup -B xxx.xxx.xxx.255 serversname
	querying serversname on xxx.xxx.xxx.255
	name_query failed to find name serversname

ifconfig eth0

	shows Bcast: xxx.xxx.xxx.255  Mask:255.255.255.0
	inet addr:  is correct

I have ipchains and iptables stopped.
