You don't want to put the shortcut on the network.
You would put the mdb, and the mdw you used to secure it with on the
network.
You should actually split the database into frontend (all objects except
tables)/backend (just the tables). Put the backend on the network, and give
a copy of the frontend to each user.
Since you've secured it, you should split manually and not use the splitter
wizard as that will unsecure the backend.
Then you'd create a shortcut for each user on their PC with a target of
"path to msaccess.exe" "path to frontend" /wrkgrp "path to secure mdw on
network"
If everyone has installed Access and the frontend to the same location, you
can copy the shortcut to each user; otherwise you'll need to modify the
shortcut for each user.
