Hello World!

Aarthi here!

Linus and I have uncovered a very interesting cause for the BA910 issue. Certain Network Attached Storage devices can install their own software to make it seem as though they are a local drive when they are actually remote drives! The server where we made this discovery had a NetGear Storage Central 101 device which appeared to be a local drive but it was actually a remote drive. As such, whenever VSS tried to take a snapshot of the drive it would fail.

When we looked in the Windows Event Viewer, we found this error message and we would like to share it with you!

So if you find that you are experiencing VSS issues with an “Unexpected Provider Error” 0x8004230f, check that all your local drives are infact local drives and not remote drives masquerading as local drives!
