[Samba] Domain + Workgroup with same name: problem?

Hello everybody!

I finally managed to set up a Samba 3.0.1 PDC that ran perfectly in the 
test-environment. Problems arose, when I installed it in a real bureau 
On a prepared w2k client that was already a domain member one could log on to 
the domain with the administrator's account, but trying to add other w2k 
clients failed with error msgs like: "Domain controller not found."

That was strange, because the PDC was obviously there and the Administrator 
was already logged in and in the test environment adding a machine worked 
without any problems.

After several hours search I found out, that there existed some (hidden in a 
back room.. :-\) XP Home clients that were members of a workgroup with the 
same name as the domain. They were already running when I introduced the 
Samba PDC into the network. When I switched them off and restarted Samba the 
PDC could be found sometimes but sometimes not.

After messing around with what I took to be cached data on the Samba Server 
refering to WINS aso. I took the radical way and reinstalled Samba with the 
same configs but with a different domain name. That solved the problem for 

But it leaves a general problem: It looks as if you can render a PDC unusable 
if you introduce a machine into its network, that is in a workgoup of the 
same name as the domain.

So my question is:
How do I configure the Samba PDC that clients within the same network know who 
is the master of the universe and who is just an impostor? Especially the PDC 
itself should not get confused about this!

The relevant entries (I think) in my smb.conf are:
	domain master = Yes
        domain logons = Yes
        preferred master = Yes
        wins support = Yes
	os leve = 64
