samba - Jul 2008 - WINS name resolution doesn't work

I've set up my Samba PDC to act as a WINS server, because I need remote
access to it (through a VPN connection). I put "wins support = Yes"
into the
smb.conf file. As far as I know, WINS doesn't use a unique port number, so
enabling the usual NetBIOS ports (137/udp, 138/udp, 139/tcp) on the firewall
should be enough to make WINS work. I did this already.
I tried to connect to a share on my PDC through a VPN connection. My VPN
server properly sends the address of the WINS server, that's sure, I can see
the correct address in the output of "ipconfig /all". smdb and nmdb
are
bound to the wildcard address to accept connections from ppp interfaces
created on the fly. Everything seems to work correctly, but my clients
cannot use NetBIOS names, when connecting to a share. Connecting to the
server by its IP address works with no problem.
I am creative, so I decided to disable WINS and use DNS instead. After that,
name resolution worked wonderfully.
But it's not that easy... by using DNS, my PDC is not able to resolve the
netbios names of remote clients, because they don't register their names in
DNS when connecting. Is there any way to use WINS on VPN clients? It seems,
that Windows silently ignores my WINS server and only tries to resolve names
with broadcasting, which is of course not possible through a PPP connection.
Do you have any ideas?

I use Samba 3.0.28a on my PDC and Windows XP Professional on my client.

If I was you I would try to reproduce the problem without
the VPN client active. If you connect the Windows client
directly to the LAN it should make use of WINS correctly if
configured to do so. You can check this with a sniffer, or
if you have it available, use a routed LAN separate from the
one where your PDC is located. If that works fine, then the
VPN client software is very likely the one breaking WINS.

This is a big problem with samba 3.x because it's use NetBIOS for domain
logon. DNS is not supported on samba 3.x because Samba 3.x working on NT.4
technology and its only support Netbios domain name. If you want to use DNS with
Samba then you should go for Samba 4.0 it's base on Windows 2003 technology
and working like Active Directory. I am also working on samba 4.x but still it
in beta test not for production.
