You will encountered this error message when:
Scenario:-
- Running DPM 2012 SP1
- Just updated to Update Rollup 3
- Tried to update DPM agents but received an error message “Event ID 301 – The protection agent upgrade failed because the protection agent is not installed on server”
Temporary resolution:- (perform manual update)
a) On each protected server, you need to go to your DPM server. Use UNC Path: \\DPMServer \c$\Microsoft System Center 2012\DPM\DPM\agent\RA\4.1.3415.0\amd64\1033 (if using x64 os)
b)Execute DPMProtectionAgent_KB2853210.msp
c) Go to DPM Console and refresh the DPM Agent. You will be getting the status “OK”
That should do the trick while Microsoft come out with a solution on it.
