ABSTRACT:
A method and system for preventing unauthorized dynamic host configuration servers from responding to client configuration requests in an Internet Protocol (IP) network. In accordance with the method of the present invention multiple network clients are simulated within a server checker client. At least one unauthorized dynamic host configuration server is then detected utilizing the server checker client within said IP network. Upon detection of an unauthorized dynamic host configuration server, configuration requests are delivered from the server checker client to the detected unauthorized dynamic configuration server such that the unauthorized dynamic host configuration server is unable to respond to configuration requests from actual network clients.
