Hello!

Looks that I were wrong, when I said that all is OK :-(
Now I can successefully find host with nslookup:

vader:~ # nslookup center
Note:  nslookup is deprecated and may be removed from future releases.
Consider using the `dig' or `host' programs instead.  Run nslookup with
the `-sil[ent]' option to prevent this message from appearing.
Server:         127.0.0.1
Address:        127.0.0.1#53

Name:   center.p98.belkam.com
Address: 192.168.22.224



but it doesn't work with wins:
vader:~ # nmblookup -R -U 192.168.22.220 center
Unknown parameter encountered: "domain admin group"

nmbd founds name, but, I don't understand why, resturns it as expired...

There is no SGTRANS in wins.dat, I can't see it in net cache list
(btw, I don't know what this command do ;-)  )

but, sometimes I see this name in  log.nbmd:

 SGTRANS<00>         TTL = Mon Mar  8 11:08:08 2004         10.1.1.6  4
 SGTRANS<20>         TTL = Mon Mar  8 11:10:43 2004         10.1.1.6  4
