We get the following error sporadically, and it seems to always deal with an Exchange Server service stealing the DPMRA port. Is there any way to get this to stop. We have to put the mailbox server in 2010 into DAG maintenance and restart services. This is not optimal. The below error is what we receive. Seems to be the Microsoft Exchange Replication Service:
DPM failed to communicate with servername because of a communication error with the protection agent. (ID 53 Details: Server execution failed (0x80080005))
We run DPM 2012
Thanks
