I have an NT 4.0 system running 5.1.6.0. (Please hold the laughter)  This 
server will not backup one of its hard drives.
The system has drives C: - N:, drives C D E J & M are hard drives, all other 
drives are CD-ROMs.  Only drive M is not backing up.
I have tried domain all-local, domain C: D: E: J: M:, and include m:\*.  The 
include generates "Sending of object '\\server\m$' failed".
My next move is to upgrade to 5.1.7.0.  Is there something else I should try?
