Hi and Welcome to the board.

There is no easy way (if possible at all) to start a script when a user tries to access a certain drive or printer that is not there yet as far as I know.
We have something set up for our VPN users but is does require a manual action from the user.
They can login from any location outside our offices and browse the internet and access their e-mail and stuff but as soon as they need a network drive or printer they runs a shortcut from their desktop that starts the logon script and maps drives and printers. Creating a shortcut is easy. Check out the WSHShortcut UDF in the UDF section. We link it to a cmd file that starts the script. A dynamic check is done to see if the VPN client is installed and if it is it checks if a site is configured. When all checks are positive a shortcut is created otherwise the shortcut is deleted if it exists.
