Cause

This issue can occur when the Virtual Disk service does not start in the Windows guest operating system on the affected virtual machine.

Resolution

To resolve this issue, start the Windows Virtual Disk service:

  1. Log in to the Windows operating system as an Administrator.
  2. Click Start, type services.msc, and press Enter.
  3. Right-click the Virtual Disk service and click Start.

  1. Disable the VMware Snapshot provider service in the guest operating system.
  2. Restart the Volume shadow copy service.
