VSS error Event ID 8193 RRS feed

  • Question

  • Good Morning to all

    I have received the error below from my server 2008 R2 Standard SP1 with Microsoft Exchange 2013:

    Volume Shadow Copy Service error: Unexpected error calling routine ConvertStringSidToSid(S-x-x-xx-xxxxxxxxxx-xxxxxxxxxx-xxxxxxx-xxxx.bak).  hr = 0x80070539, The security ID structure is invalid.

       OnIdentify event
       Gathering Writer Data

       Execution Context: Shadow Copy Optimization Writer
       Writer Class Id: {4dc3bdd4-ab48-4d07-adb0-3bee2926fd7f}
       Writer Name: Shadow Copy Optimization Writer
       Writer Instance ID: {b496f994-497d-42d6-ace2-7addf6254489}

    I have read that to resolve this issue just delete the registry key with .bak on ProfileList and then restart the server.

    Here my questions:

    Could the delete create problem to VSS or Exchange since the old user was a domain admin?

    It is necessery restart the server after the process?

    Thank you.
