Hello,
Please let us know whether you have lotus domino.
If yes then are you selecting Advanced Open File Option while backing up the Lotus database, if so, deselect AOFO. You need not select AOFO when backing up databases which are backed up by their respective agents.
Also please try uninstalling domino agent and then reboot the server and then try installing the domino agent again and then observe the result.
Thanks,
