A network apparatus is provided that is capable of requiring a reservation for an access right to a peripheral device that is not yet connected to the network apparatus from one of the terminals on a network. A server (network apparatus) may receive a reservation command and a sender identifier (ID) from one of the terminals on the network that requests to reserve an access right for a peripheral device that is not yet connected to the server. In a case where a new connection of a peripheral device is detected, the server allows the terminal identified by the sender ID that accompanied the reservation command to access the peripheral device. While the reservation is established, access to the detected peripheral device from senders other than the identified terminal is rejected.
