Resolve

Ensure that the computer is running in normal mode and that the VSS service is enabled

Volume Shadow Copy Service (VSS) can only run if Windows is in Normal mode.

In Normal mode, check whether the VSS service is enabled.

To perform this procedure, you must have membership in Administrators, or you must have been delegated the appropriate authority.

To ensure that the VSS service is enabled:

  1. Click Start, click Administrative Tools, and then click Services.
  2. In the results pane, double-click Volume Shadow Copy.
  3. Ensure that Startup type is set to Manual.
  4. Click OK.
