Correction.  It works except when doing a "cp -p" e.g.:

   cp -p /c/Local/Path/File.txt /i/network/path/File.txt

I have write permission at both the source and destination.

On the other hand, using tar to transport a file from the local directory to 
the network directory seems to work:

   cd /c/Local/Path
   tar cf - File.txt | ( cd /i/network/path ; tar xf - )
