When you put the IP address of the WINS server into the WINS addresses on
each Windows client did you reboot the remote windows client?
When the client rebooted, did that machine then appear in the wins.dat
file? If not, did you sniff the local network segment on which the WINS
server is located to see if it was receiving the name registration from
the remote windows client as it restarted?
If the remote name registration was not received, is the remote Windows
client able to ping the WINS server? ie: Is routing correctly configured?
If the netbios name registration request packet was received from the
remote Windows client, set the "log level = 5" on the WINS server, repeat
the exercise, and find in the nmbd logs what it did with the name
registration request from the remote Windows client. By rights it should
have added it to the wins.dat database. You can confirm this by using
Additionally, check that the from the WINS server you can ping the remote
Windows client by IP address. ie: Routing is set up correctly.
Also, check that you can ping the remote Windows client by netbiod name.
To enable this you need to install in libnss_wins.so in /lib, you will
also need to set in /etc/nsswitch.conf:
hosts: files dns wins

Nope. MS Windows clients register themselves at start-up. This is
documented in the new Samba-HOWTO-Collection.pdf that shipped with
Samba-3.0.0RC1 last friday. See chapter 10.
