[Samba] nmbd strange port error please help

[David Gardi]

Hi people,
I'm using samba 2.2.3a-7 on kernel 2.4.18. I have a small LAN of simply 
two humble computers.
I can log on to the other machine using smbclient view shares using the 
-L option and so on. But when I do a -M it tells me:

added interface ip=192.168.1.1 bcast=192.168.1.255 nmask=255.255.255.0
added interface ip=192.168.1.2 bcast=192.168.1.255 nmask=255.255.255.0
Got a positive name query response from 192.168.1.2 ( 192.168.1.2 )
session request failed

I suspect the problem derives from the fact that nmbd is not running 
simply because it won't start. This is syslogs output when I run nmbd:

May  5 17:17:41 vxi nmbd[27785]:   ERROR: Failed when creating subnet 
lists. Exiting.

However sometimes it doesn't give this problem and it does start 
beutifully, smbclient -M works and all is well. There's nothing unusual 
about by smb.conf so I don't think the problem lies there. I've googled 
around and viewed some of this lists' archives and have noticed that 
others have had similar problems, but no one has come up with a sensible 
solution other than modify samba's source code and make it use a port 
other that 137.

Any ideas would be absolutely great.
TIA

David.
