A system and method for monitoring the status of a network by disconnecting a user computer (102) that is in communication with the network (11) and ceases to display an advertisement window. The user computer (102) displays advertisements in an advertisement window while in communication with the network (110). The user computer (102) periodically generates notification messages while the advertisement window is displayed. A monitoring computer (106) is in communication with the user computer (102) and is configured to receive the periodically generated notification messages and store the messages in a database of received notification messages. The monitoring computer (106) periodically compares the database of received notification messages to a database of user computers (102) which are in communication with the network to identify the user computers (102) which are not sending the notification messages. The monitoring computer (106) disconnects the user computers (102) not sending the notification messages.
