Hey guys

Having a weird issue with our work server that I setup (somehow, as I'm new to the server realm).

Basically, I've managed to get all the little errors ironed out, all except for this annoying VSS Error that seems to only happen between 8PM and 6AM.

This is the error message I get:

VSS Error 8194
Volume Shadow Copy Service Error: Unexpected error querying for the IVssWriterCallback interface. hr =0x80070005. Access is denied. This is often caused by incorrect security settings in either the writer or requester process.

Now I have no idea what this means nor how to fix it, so I'm hoping some of you clever people can give me an idea of solution. Greatly appreciate all and any help received.
 
I believe it does coincide with livedrive backups yeah. Just ran the Vssadmin list writers and it's reporting no errors.
 
Do you mean "add string"? As when I add key, it creates a subfolder. Have confirmed it is our backup program causing the errors now!
