[Samba] Samba Replication problem between two DCs

Tue Oct 29 10:14:56 UTC 2019

I'm pretty sure this is a resolving problem.  

Can you verify this: 
https://wiki.samba.org/index.php/Verifying_and_Creating_a_DC_DNS_Record 
Especialy these : for both guids and cross check if from both servers. 
host -t CNAME 50507d18-c8ee-4ef4-bbda-4d0d9bc31caa._msdcs.....  

Can you post from both server. 
/etc/hosts
/etc/resolv.conf

host servername
host fqdn

host servername @dns othere server
host fqdn  @dns othere server

repeat the post part for the other host. 

Greetz, 

Louis
