Event ID 12302: Volume Shadow Copy Service error

I ran into a issue today with Data Protection Manager 2007. When I tried to create a new protection group and select members I got

The Operation Failed bacuse of a protection agent failure
Retry the operation
ID: 998
Details Unknow error (0x80042318) (0x80042318)

on the member I found this error

Volume Shadow Copy Service error: An internal inconsistency was detected in trying to contact shadow copy service writers.  Please check to see that the Event Service and Volume Shadow Copy Service are operating properly.

The workaround I found was to (on the member server)

  1. Backup the follwing regkey: HKLM\Software\Microsoft\EventSystem\{26c409cc-ae86-11d1-b616-00805fc79216}\Subscriptions
  2. Erase the regkey
  3. Reboot.
  4. Verify that things are working by running “vssadmin.exe list writers”

The deleted regkey will be regenerated after reboot.

Remeber to install article ID 940349 on the server you are trying to protect, else you will get an error about pre requirements when trying to select members to a proction group. At this page you can see all Software Prerequisites for different kind of workload.
