samba - Dec 2001 - Samba/Win_NT mapped drive problem

I am having a problem with Samba 2.2.2 mapped drives under Windows
NT.  

Specifically, the problem is that users cannot either read directly from
(by double-clicking on a file), nor directly write to the root of a mapped
drive.  Users CAN however create a folder in the root of their mapped
drives and then read and write files to that folder okay, and can also
copy files from the root of their mapped drive to a local drive by either
dragging and dropping or right-clicking and selecting copy/paste.

Under Windows 2000 the problem simply doesnt exist - unfortunately at the
moment I cannot upgrade everyone currently using Windows NT to Windows
2000 due to some software issues.

For example:

P:\new_folder
	|
	---- some_file.txt

is fine, both reading by double clicking and writing

P:\some_file.txt

isnt!

The error I get when trying to copy a file to the root of the mapped drive
is 'A file with the name you specified already exists. Specify a different
filename'.  The error I get when double-clicking a file is 'The
directory
name is invalid'.  The error I get when attempting to cut and paste a file
into the root of a mapped drive is 'Cannot create or replace P:\: Root
directory (internal error)'.

Has anyone else seen these problems before?  Perhaps more importantly,
does anyone know how to solve the problem?



I am running Samba 2.2.2 acting as a PDC.
The Windows NT machines are running NT 4.0 SP6.0a
The WIndows 2000 machines are running Windows 2000 SP2

smb.conf file attached below.
