ABSTRACT:
A method for notifying a client device of termination of at least one service provided to the client device by a server system within an enterprise network is disclosed. The method includes the step of establishing authentication data and notification data, where the authentication data is related to the notification data, and sending the authentication data to the client device for storage during a provisioning operation. When the server system identifies a termination of service, it sends the notification data to the client device, which may then authenticate the received notification data using the authentication data.
