A VSS Writer has rejected an event with error 0x800423f3

Recently I hit the issue for the DPM backup the VMs.  The DPM backing the Hyper-V VMs failed with the following message in the event viewer of the Hyper-V host that the VM is residing.

Then in the command prompt (elevated “run as administrator”) I list the VSS by typing the command Vssadmin list writers.

In the DPM console, had the following :

The steps that I took to resolve the issue is as follow :

• Shutdown the VM
• Perform the VM backup through the DPM
• In the Hyper-V host, launch the Hyper-V Manager and would be able to see the status as “backing up …”
• Once the backup is completed in then I start up the VM.
• Waited for 20 mins for the VM to be up and running, then perform another backup (create another recovery point in DPM)
• It’s successful and case is resolve.

In the Hyper-V Host I run again the command prompt (elevated “run as administrator”) by typing the command Vssadmin list writers and check the status.

Hope it helps.
