Hello,

I am trying to modify protection group. I received error ID 917: Connection to the DPM service has been lost issue. I am running DPM 2016 version 5.0.622.0.

Any ideas on how to resolve this issue?

Appreciate any help I can get.

The description for Event ID 999 from source MSDPM cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.

If the event originated on another computer, the display information had to be saved with the event.

The following information was included with the event:

An unexpected error caused a failure for process 'msdpm'. Restart the DPM process 'msdpm'.

    Hi,

    I had a similar issue. Error id was 917: Connection to the DPM service has been lost.

    It turned out that I had been using DPM 2016 with DB on SQL 2012. DPM was fine with it up to UR9, but after update to UR10 DPM console started to crash.
    This documentation states that DPM 2016 does not support SQL 2012 since UR2:

    After SQL server upgrade to MS SQL 2016 it is looks like the issue with console crash has been solved.

    Hope it would be helpful.

    Hi,

    Thank you for posting your query.

    To work around this issue, create a protection group that contains all the SQL Server Always On databases. (If you have to adjust protection group settings, you should make the change when no jobs are running.) After the error occurs, restart the console, and then resolve the warning. At that point, the protection group will return to OK status, the new settings will take effect, and future backups will succeed.
