SOLUTION: When it is estimated that a setting mistake is present in a network setting file F2, the network setting of a device 3 is returned to the state of a network setting file F1 earlier than the network setting file F2. When the network setting file F2 is updated without a setting mistake in network setting operations OPk to OPk+4, restoration of the operations is requested to the device 3 through a management server 2. In the device 3, the network setting file F2 is restored to the middle by reflecting the requested network setting operations to the current network setting file F1. COPYRIGHT: (C)2008,JPO&INPIT
