A license management system and method for recording the use of a licensed product, and for controlling its use in accordance with the terms of the license. A licensed product invokes a license check monitor at regular time intervals. The monitor generates request datagrams which identify the licensee and the product and sends the request datagrams over a communications facility to a license control system. The license control system maintains a record of the received datagrams, and compares the received datagrams to data stored in its licensee database. Consequently, the license control system transmits reply datagrams with either a denial or an approval message to the monitor. The monitor terminates further use of the product if it receives a denial message. The monitor generates its own denial message if its request datagrams are unanswered after a predetermined interval of time. The datagrams are counted at the control system to provide billing information.
