[Samba] Replication fails

[Tobias Haas]

Okay, after setting /etc/hosts entries for both DCs (IP guid_msdcs.x.y.z) 
manually, at least part of it seems to work. So name resolution didn't work 
right, although host -t CNAME guid_msdcs.x.y.z showed correct entries.

But there is still the problem with "Warning: No NC replicated for 
Connection!". Is this normal?

Best regards,
Tobias
