Thanks for your answer. I played with my network (I can do it, because it is
only for testing and learning purposes) and found the followings:

My Windows client do use the WINS server specified, it seems, the only
problem is, that my PDC somehow forgets to register itself in WINS. Look
what I get if I try to join the client to my domain (the client is on a
different subnet as Samba is listening on):

So, according to this, the WINS server of Samba works okay (the client found
the domain), but it cannot resolve the name of my PDC for some reason. So
this must be a server-side problem. Am I right?

I'm going to check the logfiles on my PDC thoroughly and tell you what I
