[Samba] hide unwriteable files and windows xp

[Witt, Terry]

I need to hide the listing of files to multiple users, but only allow access to the file if you know the exact path and filename of the file in the form of \\server\share\filename.txt.  I am using the hide unwriteable files = yes flag to accomplish this and it works as expected with windows 7.  However, windows XP gives the error that windows cannot find the file.  Is there a different setting, or perhaps a different way to accomplish the same results, that works with windows xp?
