Our environment is probably a little different than most, in that we
are using Samba as a fileserver in a university computer lab
environment. Windows clients are Win2K and XP boxes and they are set
up in a sort of "kiosk/public terminal" mode for student access in the
labs - students don't login to get to the desktop or use the internet,
they can simply sit down and begin using the pc. To access their
samba directory, we have set up an icon on the desktops with the UNC
path to the Samba server, which, when clicked. does prompt them for a
username and password, and accessing it this way works great.

The problem is disconnecting the client from the Samba server after
the student is finished. We would prefer the students NOT have to
start/run/logout as they leave the workstations - doing so means we
have to run around constantly logging the machines back in. What we
want is an icon on the destop that, when clicked, disconnects the
Samba share. Thought I had the answer with a "net use" batch file on
the desktop (net use * /del) but this is where things get weird. When
I run the net use * /del command, I get a message at the command line
that says all connections have been terminated. If I run "net use" at
the command line, I also get the same message about connections. BUT
- if I double click the icon for the Samba server, I am immediately
taken back to my share without being prompted for a username/password!
It should prompt me for username and password, but intstead appears to
be caching the connection somehow.

So, in a nutshell - we're looking for a way for our students to
immediately diconnect from samba without having to do a
start/shutdown/logoff, so that the next student who sits down at the
pc is prompted for a username and password.

Any ideas? Thanks,
Dave
