nmbd *was* running:

deveis # /var/install/bin/samba-pdc-groupmapping -q addall
deveis # nmbd -D
deveis # smbd -D
deveis # ps ax | grep mbd
  1420 ?        Ss     0:00 nmbd -D
  1422 ?        Ss     0:00 smbd -D
  1423 ?        S      0:00 smbd -D
deveis # ls -l /var/lock/samba/unexpected.tdb
ls: /var/lock/samba/unexpected.tdb: No such file or directory
deveis # net lookup -d10 'tb3#00'

If there is an cache entry for the name and the cache entry isn't 
timeout, then no packet is sent on port 137 and the error messages are 
not appearing:
