[Samba] replication issues solved by adding GUID names to /etc/hosts

Wed Aug 27 02:15:57 MDT 2014

Ok.. wel and your sure the resolv.conf is correct?  
cat you post the hosts file and resolv.conf file. just to be sure. 

i noticed, ( sernet samba) that after adding a DC, the replication didnt work right a way.
It needed a restart of the server. This was tested with server samba 4.1.4-4.1.9 
and after the restart replication started working. 

Greetz, 

Louis
