Given a path determine root of drive or mount point

Hi all

What I'm looking for is to determine: Given a path (IE: c:\program
files\exchsrvr\mdbdata) is the root of the drive c or is it a mount
point (IE: a drive mounted at the exchsrvr folder)

I think it is possible to, given the path of mount point, to check it is
a mount point, but not if the path given was one deeper.

If this were not a vbscript program, the answer would be at:
http://msdn.microsoft.com/en-us/libr...96(VS.85).aspx
That appears to do the job perfectly, I just don't know how to use it in
vbscript!

The only other thing I can think of is to get the path, remove one
folder at a time, check for a mount point, and repeat, until we find the
root or a mount point.

I've been looking at win32_logicaldrives, and win32_mountpoint,
win32_diskdrives, win32_volume, but none of these seem to just 'fit'.

Any suggestions?
