I've two windows 2008 r2 active directory domain controller in two different places connected through a vpn connection. Sometimes i receive RPC Errors ("RPC services not avaible") and the replica doesn't work correctly. Sometimes I've deleted the domain zone with the active directory name, I've created a new one and the replica worked correctly.
How can fix this DNS Server problem?

On your VPN are you using DNS instead of IP Address?

Have you configured DNS scavaging? How often do you receive those messages?

You need to make sure you have all ports opened so replication can take place.

If you are having issues please post dcdiag

For snusgubben: I receive this message about every 2 months. I didn't configure  DNS scavaging. Sometimes I do that manually from the dns snap-in.
What is  DNS scavaging?How can i configure it?
Thanks.


For others:
All vpn ports are opened. Usually the controller works correctly.

DNS scavenging will just clean out stale records. I was just thinking about maybe the A-record got deleted since recreating the zone fixed you up.
