Fixing DPMRA Start Failures After Installing AD DS on Windows Server 2008

Date: 06 January 2011

I’m getting ready to deploy a pair of Server 2008 Active Directory servers to replace a couple of old 2003 boxes. In preparing those servers, I installed the remote agent for Microsoft Data Protection Manager before I installed the ADDS role and promoting the new AD servers. That turned out to be a mistake.

After promoting the AD servers, the DPM agent service (DPMRA) stopped running and would not start again. Instead it would kick back the “service-specific error code 1332” or 1168. Neither was especially helpful. So, I tried Windows Troubleshooting Step #1: Reboot. No dice. A quick trip to Google and I found a few suggestions to run setdpmserver again. Unfortunately that kicked back this error.

SetDpmServer failed with errorcode =0x80070534, error says: No mapping between account names and security IDs was done. To further troubleshoot failures with SetDpmServer, go to http://go.microsoft.com/fwlink/?LinkId=169142.

Turns out, that link doesn’t help at all. Fortunately, searching on that error brought me to the troubleshooting page in the DPM docs. Therein is suggested Windows Troubleshooting Step #2: Reinstall. I uninstalled the agent, rebooted, installed the agent manually, reran setdpmserver, rebooted again, and DPMRA finally started.
