ABSTRACT:
In the present network system, a printer10periodically transmits an update request at different timings respectively to an apparatus management PC30and to a directory service50which are monitoring apparatuses for monitoring network apparatuses (such as the printer10). Each of the monitoring apparatuses30, 50determines a state of the printer10based on the update request from the printer10. Especially in the present system, if the apparatus management PC30determines that the update request from the printer10is not received, it notifies the directory service50by transmitting a delete request. As a result, early detection of disconnection of the printer10by the directory service50is possible without causing substantial increase in the network traffic.
