Ah, I found a similiar hint already in this mailinglist , but why is there already an entry ? 
I tried a vanilla samba4 AD domain and the server contacted the dc for the first time.

Any hints how to examine and identify the dns-entrys with samba-tool ? 
I'm not very common with samba-tool and samba dns yet :-) 

Thanks in advance,
