Error:8193 Source:VSS

We have a terminal Server with windows server 2008 R2 Standard. We found that we keep receiving the Error 8193 with Source VSS.

The error (Event 8193) is: Volume Shadow Copy Service error: Unexpected error calling routine ConvertStringSidToSid. hr = 0x80070539.

As I never like any Error in the Event viewer so I searched on Internet.

According to the research, the issue may be caused by an invalid entry inside the following registry sub tree.
Please open the registry editor with regedit. Open this Key.
HKey_Local_Machine\Software\Microsoft\Windows NT\CurrentVersion\ProfileList
Expand and local to the subtree, check if there is an entry that has a ".bak" value or ".old" appended. If so, this may be cause the failure when trying to resolve the SID of the writer.
Please backup the registry key first, and then delete that entry with the extra ".bak" and ".old".
I rebooted the problematic server to check if it the issue can be fixed.

and the magic happen..!! I observed it for 24hrs and found that the Error is not coming now..!!

Thanks DAVID..!!
