There is a known issue in VSS functionality of MS SQL 2005, which is fixed in later a service pack. Or the VSS provider is broken and needs to be re-registered.


  1. Make sure you have the latest MS SQL service packs installed for all instances on the machines.
  2. Re-register the VSS provider using following batch file:

    (!) Do not attempt this solution on Windows 2008 R2 or newer operating systems

    (!) We recommend doing a partition backup before re-registering the VSS components.
    1. Download and unpack this file: reregistervss.zip;
    2. Go to Start -> Run -> cmd -> OK;
    3. Run the batchfile.
