thanks for your explanations, I see now ;)

I already informed the responsible guys to investigate this because I 
also assumed that this is wrong.

The problem is that this domain has multiple subnets and multiple 
(B)DCs, the one on my subnet is most likely not the PDC. It is the local 
master browser but not the DMB and there is also no machine on my subnet 
that feels like beeing the DMB. Since the WINS servers (different 
subnet) do not know anything about a DMB either I am kind of lost here...

Yes, i think you are right ;)

So I have to wait for the admins to fix this.

It definetly was, thanks a lot.
