Netbench and Samba 2.2.1a

I am the colleague David reefers to below. I haven't had time
to update Dave on what I learned about this problem.

There is NO problem with Samba.

My problem was caused by the fact that NT mapped drives are not
accessible in exactly the same way by an application launched by
a Remote Shell Daemon as they are from applications that
are launched by the user from the desktop. The authentication is
some how different enough to make the drive inaccessible without
using the "security = share" smb.conf file setting. 
This problem is documented by NT version of the rshd software
( I initially missed it because 
I usually use the W98 version of the RSHD software where the problem 
does not occur.

There are other ways around the problem, but the "security = share" 
smb.conf file setting works is working fine for now.
