VM Server 2016 - Event 8193 Volume Shadow Copy Service error: Unexpected error calling routine ConvertStringSidToSid RRS feed

  • Question

  • Hello All,

    We have a virtual Server 2016 at work. Which keeps 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.
