  • VSS Not working

    After trying acronis server backup, I decided not to purchase. After uninstall, now volume shadow service isn't working. Using Server 2008 Standard 64 bit (not R2)

    I've tried uninstalling, reinstalling windows server backup. Also tried

    The dll's aren't registering. Compairing the registry to another server 2008 I can clearly see I am missing everything in this registry entry:
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\VSS\Providers\{b5946137-7b9f-4925-af80-51abd60b20d5}

    Can I copy and merge the entry to the server that isn't working or is there a better solution?

      Says it imports sucessfully but still isn't there after a reboot.

      I tried the steps in this article (
      and everything (including backup) seems to be working. I am just thinking that with that registry entry missing I may be sitting on a time bomb.

      Anything else I shoudl try or any test I can do to be sure VSS is working?
