Event 8193 Volume Shadow Copy Service error: Unexpected error calling routine ConvertStringSidToSid RRS feed

  • Question

  • Hello All,

    We have a reoccurring event 8193. From what I could gather on line this is regarding a backup issue with the SID. Non the less, would like to cover all my bases since have not found anything specific for this faulty module.

    Can someone help me out with the basics: Where is this coming from? Do we need to take up any measures? is this high impact? how to resolved if needed.

    Thank you all in advanced.

  • Hi,

    Please make sure that all your VSS writers are in stable state, you can check it with the following command:

    VSSadmin list writers

    This issue may be caused by an invalid entry inside the following registry sub tree:

    HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\ProfileList

    Please open the registry editor by typing "regedit" in Run or in the Stary Menu.
    Then expand and navigate to the above registry subtree, check if there is an entry that has a ".bak" value appended.

    If a ".bak" value exist, this may be cause the failure when trying to resolve the SID of the writer.

    Please backup the registry key first before doing any changes, then delete that entry with the extra ".bak", and  finally reboot the problematic server and check if the issue is resolved.


    Best regards,
    Leon

    Thanks for posting in our forum!

    1. What backup tool do you use? if you use the third-party backup tool, please contact the tool veendor to seek help.

    2. Please run "vssadmin list writers" and upload your screenshot.

    3. Please try to uninstall AV software and try again.

    4. For error event 8193 usually indicates that an unexpected Volume Shadow Copy Service (VSS) error has occurred

    And according to your error message, it is related to that the .bak file is not working as expected.

    Sine the failure may related to resolve the SID of the writer, we could backup the registry key first, and then delete that entry with the extra ".bak

    And if you are consider about the problem, as suggested before, please backup the registry key first, you could restore the registry key to the original one in case something wrong.

    Hope this can help you, please let me know if you have any question.

    Best Regards,

    Daniel
