NMB problems

[Sebastian Sanchez]

Hello, I am having some trouble with NMB. My linux box doesn't appear in the
network neighbourhood (win 98).
In spite of this, I can still access the linux shared directory.
I have tried almost everything and lately I have been seeing this message in
the log.nmb file:

[2000/03/03 17:11:11, 1] nmbd/nmbd.c:main(672)
Netbios nameserver version 2.0.3 started.

Packet send failed to 192.168.0.2(138) ERRNO=Network is unreachable

The strange thing to me is that this IP address is not in my network. who is
telling smb to send this packet to that IP address?
I have already searched for this IP in almost every configuration file
(hosts, lmhosts, smb.conf, etc)
My network is formed by two machines linked by an UTP crossed cable.
samba machine: running Redhat 6.0, Samba 2.0.3

Thank you very much.
PD: Sorry if my English is not so good.
