[AccessD] Mapped Drive

 Good Morning,

   I have always been successful in mapping one of my folders on a local
drive to appear as a drive (example: M:\).

Now with Win 7, I have had no luck in writing and sometimes reading the
resulting mapped drive.

I am pretty sure it has to do with some aspect of user/admin rights.

But when I change and modify the properties of the mapped drive, I still am
not able to use it.

It's very important as I, like most of you, need to replicate a clients
setup so as not to have to redo links and other operations. 

Like Barry found out (libraries), I am sure that this is another instance of
MS protecting us from ourselves.

 ????s

 What is the secret to this ? 

Best,

Bob Heygood
