Has anyone else noticed this?

I have a user that is using the DOS SUBST command to assign
a drive letter to a subdirectory.   When he runs the windows
client, it won't back up because it sees two separate drive
letters (in this case C: and Z:) with the same Volume Label.

Any suggestions as to what to do?  I don't think it's
reasonable to expect him to change his PC setup just to
be able to back up his machine.
