I have set up a PDC using opensuse 11.1, as network browsing I was using broadcast and everything was working fine, now I have added wins support = yes and name resolve order = win bcast …
but now sometimes I get an access denied message when trying to access the server via network neighbourhood, I have enabled, samba server, DHCP server and Netbios in the firewall, note that the wins server address is given to the windows XP workstations via DHCP and when I check status, support, details the workstation has the wins server address, this is not always but very often.

Does the PDC have a static IP? If not it could be that old IPs are being
used by clients.
On the PDC check the contents of “/var/lib/samba/wins.dat”. Are the XP
boxes and PDC listed? Is the domain name, (1b,1c) being assigned the IP of
the PDC?
When an XP client fails to connect, on the client(command prompt) run:
nbtstat -r
You should see what is being resolved by Wins and Broadcast as well as if it
is registered.
Also check the contents of “/var/log/samba/log.smbd”
& “/var/log/samba/log.nmbd” to see if something pops up. For debugging it
might help to set the parameter “log level = 1” (also try level 3 if you need
to) in /etc/samba/smb.conf. Be sure to restart smbd after changing the conf.

yes it has an static IP

yes it has the windows xp box and the PDC IP
Is the domain name, (1b,1c) being assigned the IP of the PDC?
yes but only in 1c not in 1b
what means 1c and 1b?
there were some extra virtual network adapters because I have vmware installed so I removed them, and in fact those virtual NIC were in the wins.dat file, I dont know if that was causing confusion, I didnt have the time to make more than 4 test and it was working fine.

domain_name1B is the domain master browser.
domain_name1C is the domain controller.
Do you have “domain master = yes” in /etc/samba/smb.conf? If not make it so.
Also be sure you have “preferred master = yes” (or the default auto)
and “local master = yes” (this is the default value).It might help to execute
the following:
testparm -v /etc/samba/smb.conf
This will return all the parameters (including defaults) in your smb.conf. It
is always possible to have a typo and you did not actually set a parameter
that you meant.

The above look good.
It could well be the virtual network that is causing problems. If the
instability persists you might want to take a peak with “Wireshark” (formerly
Ethereal)

One more thought, you should check /var/log/samba/log.nmbd to see if Samba is
losing the browser elections for some reason. You might need to increase to
log level to at least 1(one)in order to see this. This is done by adding to
your smb.conf the parameter: log level = 1 . Restart nmbd after you do
this. If Samba is losing the election please post back.

the IPs 192.168.137.1 was the IP of the virtual NIC, I remove it but the wins.dat was not fixed so I delete it and a new one was created with this content
this is the entry of the nmbd.log before fixing the wins.dat file

The question is, How can I flush all that bad and old entries from the wins.dat file without having to delete it or restarting the server?

It kind of looks to me like it has been done. The wins information is also
in: /var/lib/samba/wins.tdb. If the bad entries return you may need to
delete both wins.dat and wins.tdb the restart nmbd.
su
rcnmb restart
You can make the windows clients reregister with
nbtstat -RR
