[Samba] nmbd is not working

[Taki]

Hi,

I'm having a hard time running samba.  I was going through the
DIAGNOSIS.txt, and found that on test 4, "nmblookup -B..." returns nothing.

I was trying to run samba from swat's status.  smbd seems to work since
when I click start button, the daemon appears on the list, but nmbd doesn't.

I was thinking that nmbd was incorrectly installed as described in 
DIAGNOSIS,txt, but how many times I redownload samba, nothing changes.

I'm using samba 2.2.6 on redhat 7.3.

Thanks in advance

Taki
