An image forming apparatus stores a settings keyword, receives a Probe message including a search keyword from a client apparatus via a network, retrieves the search keyword from the Probe message, determines whether or not the search keyword from the Probe message matches the stored settings keyword, and transmits a ProbeMatch message to the client apparatus if the search keyword from the Probe message matches the stored settings keyword. Further, the image forming apparatus stores setting data, searches for another image forming apparatus having a function of transmitting the setting data based on a keyword search using WS-Discovery, requests the setting data from the specified another image forming apparatus, generates new setting data based on the setting data received from the another image forming apparatus, and stores the new setting data.
