Abstract: The devices including image forming devices are remotely managed by a management apparatus through communication. The communication is often interrupted during the remote management of the devices. One exemplary cause for the interrupted communication is an intentional temporary power supply deactivation of the managed devices by the user in the attempt to reset the devices in trouble or malfunction. The interrupted communication is promptly and accurately recovered subsequent to the activation of the power supply based upon a predetermined monitoring device such as a communication in-progress flag.
