File permission error while trying to run NTBACKUP

Whenever I try to run an NTBACKUP job, it backs up C: and D: drives fine,
however it always fails on S: drive with the following error - "S: is not a
valid drive or you do not have access to it"

When I browse My Computer, S: IS a valid drive, and I DO have access to it.
It has about 6-7 folders in it and I can open, browse and write to each
folder in it. I also verified that I have full permissions to the foler.

I've pasted below the NTBACKUP LOG and also the EVENT LOG

Thanks for any help,

--------------------------------EVENT LOG--------------------------------
 
Although you don't say so, I suspect that you're running ntbackup
as a scheduled job. Scheduled jobs run in their own environment
and just because you have drive S: in your own session does not
mean that drive S: exists for the scheduled task.

You should use UNC coding for scheduled jobs instead of drive letters.

Pegasus, thank you for the quick reply. The job was running as a scheduled
job, but during my troubleshooting I ran it as a manual job and got the same
results. The S: drive is actaully a partition and not a share, therefore I'm
not able to use a UNC path.

When running this backup job (either manually or under
the Task Scheduler), embed it in this batch file like so:

@echo off
echo %date% %time% Start of task > c:\test.log
echo User=%UserName%, Path=%path% >> c:\test.log
dir S:\ 1>>c:\test.log 2>>&1
dir C:\ > c:\test.txt
copy /y c:\test.txt S:\ 1>>c:\test.log 2>>&1
ntbackup /.. /.. /..
echo %date% %time% End of task >> c:\test.log

Now run this batch file, then examine c:\test.log in
detail. I suspect that everything will become clear.
