samba - Nov 2003 - How to change the IP adresse answered by "nmbd"

Hello,

I am installing Samba on a TruCluster (HP).
>>> The cluster have two members:
	FRODON:
		IP to company network : 10.0.50.12
		IP for Cluster interconnect 172.31.1.1 (only connected to
SAM)
	SAM:
		IP to company network : 10.0.50.13
		IP for Cluster interconnect 172.31.1.2 (only connected to
FRODON).
>>> The clusters name is HOBBIT and it use the IP adresse 10.0.50.18.
>>> DNS entries are:
	frodon	10.0.50.12
	sam	10.0.50.13
	hobbit	10.0.50.18
>>> I have the following configuration on smb.conf:
BEGIN
----------------------------------------------------------------------------
-------------------------
[GLOBAL]
	....
	netbios name = hobbit
	....
	socket adresse 10.0.50.18
....
END
----------------------------------------------------------------------------
-----------------------------
>>> nmbd is running on FRODON
>>> The command "nmblookup -U frodon hobbit" from a other
UNIX station give
me the following result:
BEGIN -------------------------------------------------------------
queriyng hobbit on 10.0.50.12
10.0.50.12 hobbit<00>
172.31.1.2 hobbit<00>
END ----------------------------------------------------------------



What do I have to change to got an answer like "10.0.50.18 hobbit
<00>" ?

Thanks
