Give the users permissions to the share, and if you want it to run for every
user on a per-machine basis, the easiest way is to put a .bat file in the
all users startup directory with contents like:
net use q: /d
net use q: \\server\share /p:n
You may want to adjust the permissions so that users have the rights
necessary to have the file run, but cannot modify it or delete it.
