Same error here.
It was working fine until last Friday Jan 26 2007. I have Win2003 Std Edition, SP1 and BE 10.0 Rev 5520 SP1, Hot fixes 13 and 15. I am NOT running MS Exchange in this server. The System Event Logs don't show any backup related errors.
The error is this:
AOFO: Initialization failure on: "Shadow?Copy?Components". Advanced Open File Option used: Microsoft Volume Shadow Copy Service (VSS).
Snapshot provider error (0xE000FED1): A failure occurred querying the Writer status.
Check the Windows Event Viewer for details.
