      1. If you are on campus and connected to the network, use the Windws Search for look for and launch 'Software Center.'  Once software center opens, look in the list of the Application tab for FortiClient.  Open it and click on install.  Once the install completes, you will need to reboot your PC to complete the configuration

  6. FortiClient does not work while on campus
    1. As FortiClient is designed to connect you to the USJ network from the outside, it is not required and will not work while on a USJ campus.
  7. Mapped network drives show a red X when you open File Explorer
    1. Because your PC will attempt to connect to network drives at login (before VPN connection) it will note that these drives are not available with a red X.  The system will not attempt to reconnect to these drives until you ask them to by trying to open them.  Simply double-click on the drive to request that the computer reconnect, and the drive should open and remove the red X
    2. If you still see a red X and the drive does not connect, check your FortiClient window and ensure it still shows that you are connected.  Reconnect if you have been disconnected.
    3. If the connection is good, and you are still not able to open the drives, open a ticket with the Service Desk here - Problem with FortiClient VPN
