DPM 2012 Agent Update failure
We recently had our DPM server upgraded from 2010 to 2012 (by an external consultant).
Initially all was fine. Then over the weekend there were multiple errors with the backup which were essentially all of the same type:
The protection agent on server is not compatible with the DPM version. The protection agent version is 3.0.7696.0, and the DPM version is 4.0.1908.0. (ID 904 Details: Internal error code: 0x80990911)
Oddly when I look in the Management panel it shows all the affected servers as having the current DPM agent.
I'm wary of manually deploying the agent on the affected servers in case this is going to cause more problems. I am waiting to hear back from the consultant that did the upgrade, but thought I'd just check here to see if anyone has come across this before. Google isn't turning up much, if anything.
