Error events are generated when you try to perform a system state backup on a Windows Server 2003-based computer


If you have more than one provider registered on a Windows Server 2003-based computer, the Volume Shadow Copy Service tries to start the providers in the following order:
  1. Hardware provider
  2. Software provider
  3. System provider
However, if the hardware provider cannot be started for some reason, the Ntbackup tool cannot perform a system state backup as expected. Additionally, the following events are logged in the Application log:


To resolve this problem, generate a list of providers that are installed on the system. To do this, run the following command at a command prompt:
vssadmin list providers
This command generates the following output:
Provider name: 'Microsoft Software Shadow Copy provider 1.0'

Provider type: System

Provider Id: {b5946137-7b9f-4925-af80-51abd60b20d5}

Note This is the default output only if the in-box Volume Shadow Copy Service system provider is installed.

If the command returns additional providers and if you experience any of the error events that are described in the "Symptoms" section, contact the vendor to determine whether an update is available for the provider in question.

To configure the Ntbackup tool to use the in-box Volume Shadow Copy Service system provider as the default provider, follow these steps:
  1. Click Start, click Run, type regedit , and then click OK.
  2. Locate the following registry subkey, and then right-click it:
  3. Point to New, and then click DWORD Value.
  4. Type UseMicrosoftProvider as the name for the new DWORD value, and then press ENTER.
  5. Double-click UseMicrosoftProvider. To enable the new feature, type 1 in the
    Value box. To disable the new feature, type
    0 in the Value box.
  6. Press ENTER, and then exit Registry Editor.
  7. Restart the server.
  8. Use the Ntbackup tool to perform a system state backup.
