Event ID 512 The Cryptographic Services service failed to initialize the VSS backup "System Writer" object.

Resetting the Security Descriptor for the COM+ Event System service:

1. Start an administrative command prompt
2. Run "SC.EXE SDSHOW EVENTSYSTEM" without quotes and document the current settings in case you need to restore the security descriptor
3. Once you have backed up the current settings run "

Sc.exe sdset eventsystem D:(A;;CCLCSWRPWPDTLOCRRC;;;SY)(A;;CCDCLCSWRPWPDTLOCRSDRCWDWO;;;BA)(A;;CCLCSWLOCRRC;;;IU)(A;;CCLCSWLOCRRC;;;SU)S:(AU;FA;CCDCLCSWRPWPDTLOCRSDRCWDWO;;;WD) " without quotes to add the missing permissions for the Service Logon User.

4. Restart both the COM+ Event System and Cryptographic Services
5. Now run "VSSADMIN LIST WRITERS" You should now see the presence of the System Writer
