My backup software always fails when attempting to use VSS to backup busy
files. When it does, the following message appears in the system event log:

Volume Shadow Copy Service error: Unexpected error
GetVolumeNameForVolumeMountPointW(
\\?\Volume{471e2bcf-cf8b-11db-aa57-0016e6601536}\, ...). hr = 0x80070003

When I run mountvol, besides all the expected volumes and their drive
letters, it also lists this:

\\?\Volume{471e2bcf-cf8b-11db-aa57-0016e6601536}\
The system cannot find the file specified.

I assume this is related to why VSS always fails. How can I get rid of
this? The delete option in mountvol wants to know a path, and I have no idea
how to find out what path it is that can’t be found.

I have Windows XP Professional SP2 with all current patches. I would
appreciate any clues anyone can give me about what’s going on here. Thank
you.
 
I discovered that this mount point that I thought was causing the problem is
associated with TrueCrypt (open source software that lets you create virtual
encrypted drives). Uninstalling TrueCrypt and rebooting got rid of the mount
point. I reinstalled TrueCrypt and a similar mount point appeared after the
first time I mounted a TrueCrypt volume, and remained after the volume was
unmounted. However, since I've reintalled TrueCrypt, even though the same
VSS error appears in the event log when I try to do a backup, the VSS
snapshot is now successful.
