How to return a license to the network before it expires.
Your borrowed network license is automatically returned to the network license server on the day that the license expires. You can return a license earlier than the expiry date, but to do this, your computer must be connected to the network license server.
Once a borrowed license is returned, you can borrow a license again as long as your computer is connected to the network license server and a license is available on the server.
