Exchange 2013 DAG RPC Errors when Activating DB Copies
Exchange 2013, 3 Server DAG with 4 Databases. We are having an issue with being unable to move DB copies to certain servers. I have troubleshot the issue for months and cant seem to come up with a solution. I get the error below when attempting to move databases. The odd part is the issue goes away after a few days. I can get it to go away occasionally by moving the databases to Exchange3 then rebooting 2 and moving them to 1, but if I try to move them back to 2 at that point I get the RPC error. It hits all 3 servers occasionally and I have to either reboot all of them or just wait a few days and it goes away. I cant find anything in the event viewer related and I have verified the RPC services are functioning normally.

have you checked the Microsoft Exchange Replication Service?
ASKER
Yes.
Have you tried to kill the copies and readd them? Exchange will let you know right away if something is wrong and hopefully give you something to research..
Do you have passive site also?
ASKER
We do not have a passive site. I have tried killing copies of the DB's and reseeding them.
Its seems pretty much your Antivirus is causing this issue blocking the RPC call, this is how you can validate it
1- Try opening the event viewer form another for the server had issue
2- Try remote WMI call
3- Check the DB copy status from the remote server
4- Restart the replication service on the node has issue and check the event logs
