[Samba] replication failing for 4.9.4

Fri Dec 28 15:50:03 UTC 2018

Hai, 

DC1, did you reboot it or just restarted services, i advice a reboot. 

Then on DC2. Samba internal DNS by accident? 
If so, stop samba, set log level = 10 
Start it wait 30 sec, stop it. 

Now change the resolv.conf so DC1 is the first contacted. 
and start it again. 

Test again. 

Now im out the office in 15 min, but try this.
Keep these logs, a samba dev may ask for it. 

Greetz, 

Louis
