Volume Shadow Copy Service error: Error creating the Shadow Copy Provider
COM class with CLSID {65ee1dba-8ff4-4a58-ac1c-3470ee2f376a} [0x80070422].

Volume Shadow Copy Service information: The COM Server with CLSID
{65ee1dba-8ff4-4a58-ac1c-3470ee2f376a} and name 'provider' cannot be started.


This could be caused by the following:

  • Volume Shadow Copy or Microsoft Shadow Copy Component services are not starting when a VSS operation occurs or they are set to startup mode 'disabled'
  • Microsoft Shadow Copy Component is not properly registered within DCOM.
  • Microsoft Shadow Copy Component is not correctly registered with the Operating System.


  • Verify the Volume Shadow Copy and Microsoft Shadow Copy component services are set to either manual or automatic and can be started.
  • Open the DCOM configuration tool by running "DCOMCNFG" at a run prompt and verify Microsoft Shadow Copy Component is listed under DCOM  Config, if not listed run the following to register the the necessary dll :

"regsvr32 /i%windir%system32swprv.dll"

  • Check on which Server the Snapshot Error is occurring from the Job Log. Then on the same server open Command Prompt and check the VSS Writers Status and Providers with the following commands:

                                                     vssadmin list writers - all writers should report  "Stable - No Error"

                                                     vssadmin list providers - should report Microsoft VSS if no other Hardware Snapshot Provider is being used.

If the error is being generated on a Windows Server 2003/2003 R2 machine, please install Microsoft Patch KB 940349 after downloading it from the following link:
