DPM 2016 – UR2 – MMC console crashes – event ID 999

Once you are running DPM 2016 UR2 – you may experience console crashes (services unaffected) with event ID’s 999:

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 'mmc'.  Restart the DPM process 'mmc'.

the message resource is present but the message is not found in the string/message table

These occur when adding secondary protection (DPM to DPM) to an existing Protection Group, as soon as you reach the storage calculation screen – bang, MMC crashes.

The issue resides with objectmodel.dll (in the BIN directory) – a replacement from MS was supplied and immediately resolved the issue.

If this is the case, currently the fix exists as a private hotfix only and must be obtained by logging a call with MS support.

I have asked if it will be made public and will update the blog when I hear back.

Update 10 May 2017

Premier Support have advised that the fixed DLL will be part of a future UR pack, but could not confirm if it would be UR3 or 4. So my advice is you test your environment with a few machines and see if you encounter the error – if you do, contact support and request the fixed DLL before you proceed into full production use.

      Sorry the hotfix is private and under development. Give Microsoft support a call and feel free to reference this article, they will be able to assist you.
