HIDE or Restrict access to mapped drives

If you open “My Computer” as you know you can see all local and as well as mapped network drives.

I have a situation where I need a program to access a mapped drive but I don’t want the users to see it or access it.

This mapped drive is to ashare on an AS/400 for use by Client Access Express and a program called RVI. The share has A LOT of images.

Thanks,
Andre’
