Hi

I have primary DC and a backup DC installed on a member server. I turn off the PDC intentionlly for testing. Users authenticate against the backup DC fine, however I have share mapped folders on another member server which is still authenticated against the PDC which is down. The member server can't resolve the hostname of that member server that is authenticated against the primary DC.

I added a static DNS entry in the hostfile and the shared stuff works fine, the backup DC has DNS role installed, why can't it see the hostname if its still authenticated against the PDC?

Allthough you say that the second DC has the DNS role installed did you configure the zone transfers between the two servers, sounds like it's not updating it's records.

 

Resolved it now, was a simple thing, no need for this zone transfer stuff whatever that does!

The member servers just didnt have a entry in the local DNS for the backup DC (DNS role).

Now thats been done my I dont even boot my PDC VM and everything is working off the backup DC.

Thanks for the suggestions.
