4. On the Secondary DPM Server, Agent Status for the Primary shows as Unavailable.

Detailed error code: A security package specific error occurred (0x80070721)
In a DPM 2010 primary - secondary configuration, the DPMRA service account on the primary DPM server is changed from local system to a domain user account who is also part of Local Admin group.
To resolve this issue, DPM services should be configured to run using the Local System account on the Primary DPM server.
