Running DPM 2012R2 on Windows Server 2012R2. Had to replace the fileserver and did this:
Removed DPM agent on old server
Copied all filedata to new server
Set up all shares via registry import of shares
Renamed old server
Named new server to the old servername
Installed DPM agent.
Cannot perform backups of the new server and getting the following message:

Have removed it and readded to protection group, no difference.
Have removed and readded agent and restarted server inbetween, no difference.
We do not want to remove all the previously backed up data as we need to keep it.
Does anyone have any suggestions what might be the issues here?
Thanks for comments and suggestions.
