Abstract: A management apparatus obtains setting information from a replacement target device. Thereafter, it designates a distribution mode for distributing the setting information to a new device. If a replace mode is designated as the distribution mode, the management apparatus distributes the setting information to the new device and issues a power-off request to the replacement target device. The replacement target device that received the power-off request turns off its own power. The new device that received the setting information reflects the setting information in the new device in accordance with the designated distribution mode.

Abstract: A device management apparatus acquires the state of a device (image forming apparatus), and determines whether or not an error occurring in the image forming apparatus is the already-occurred error based on the change in the state of the image forming apparatus. When the error occurring in the image forming apparatus is an already-occurred error, the device management apparatus determines whether or not the error continues for a period of time equal to or longer than a predetermined period of time. When the error continues for a period of time equal to or longer than a predetermined period of time, the device management apparatus changes an error notification destination, and retransmits an electronic mail regarding the error to the changed notification destination.

Abstract: A method, apparatus, program, and storage medium, for managing a network device by communicating with an information processing device and the network device via a network and managing the network device in response to a request from the information processing device. If a request for execution of a process, which needs particular authorization, upon the network device, is received from the information processing device, it is determined whether a command to invalidate a password of said network device has been received together with the process execution request. When the password of the network device is to be invalidated, a password invalidation request is transmitted to the network device. This technique makes it possible for an administrator of a network device to use it even when the administrator forgets the device password assigned to the network device without having to perform initialization which would cause all setting data to be lost.

Abstract: This invention provides a technique for safely and readily managing a network device. To achieve this object, an authentication server (105) performs an authentication process by using a set of a login ID and password transmitted from a manager server apparatus (103), and transmits the authentication result to a multi-functional peripheral (102). The authentication server (105) also specifies a VLAN name corresponding to this set, and transmits the VLAN name to a DHCP server (106). The DHCP server (106) determines connection setting information corresponding to the VLAN name, and transmits the determined connection setting information to the multi-functional peripheral (102). The multi-functional peripheral (102) connects to VLAN 2 by using the obtained connection setting information.

Abstract: This invention relates to a method and apparatus for managing network devices, which allow the user to intuitively recognize errors that have occurred in network devices. When an error monitoring module (701) detects any error that has occurred in a network device, a corresponding URL address acquisition module (702) acquires a URL address corresponding to an error category. An electrical generation component generates electrical message data for error information, which contains the acquired URL address, and sends it to an electrical sending module (706). Since the user can access error information provided by an HTTP server module (708) by clicking the URL address described on the received electrical message once, he or she can intuitively recognize the error contents by simple operations.
