Thanks for you reply dkrnic...

Anyway... I found the problem. (but NO SOLUTION!!)

Just to summarize...
I had a win2k sp2 machine at home and win2k sp4 machines
on my work. I was unable to login my samba-pdc (v3 rc2) with
the workstations @ work, but I was able to connect from my win2k sp2 
machine at home through a VPN connection.

I now took that machine (w2k sp2 -machine from home) to my office to
test if it would also work on the network instead of a vpn connection.
and... it didn't, it gave the same error as the other machines.

In tcpdump I saw the DNS query from _ldap._tcp.dc._msdcs.<MYDOMAIN>.
This annoyed me, because my workstation from home on VPN didn't do this.

Then I came up with the plan to disable my DNS-server in my 
network-settings on my w2k-machines. Then I tried to log on to the 
domain and.... voila... it worked. When I enable the DNS-server again in 
my configuration I can't login to the domain anymore. 

I read some things about Native and Mixed -mode w2k's. I believe this is 
the whole problem. W2k's are in Native mode looking for Active Directory 
and Samba obviously... not... since it can't.

Anybody knows how I can change this behaviour of w2k towards my PDC?

I'm not so sure. Don't blame M$ too soon. Your use of
LDAP or how you use it may be the problem.

I'm not sure it does, probably not. Do other posters
complain about PDC+LDAP+W2K-SP3-4? You can't be the 
1st one with the problem. I don't use LDAP. SPs never 
affected my clients, 2, 3, 4.

Better analyze the login transactions for both SPs 
in a higher level log to be a bit more sure what is
going on.
