A device managing apparatus that can easily communicate under a proper communication configuration, through a network may be provided. A managing apparatus is provided with a storage and a controller (management program). The storage stores multiple different communication configurations. The controller controls the communication with the device. The controller carries out the following processes: (1) repeating a communication trial toward the device using one of stored communication configurations that are stored in the device managing apparatus, in which the communication configuration to be used is changed for each communication trial; (2) monitoring a response which is sent to the device managing apparatus from the device in a case where the communication trial has succeeded; and (3) displaying a plurality of areas, each of which is linked to each of the stored communication configurations; and displaying a symbol image representing the device in the area that is linked to the communication configuration with which the communication trial has succeeded. By using the device managing apparatus, the user can easily recognize, at a glance of the screen, devices at which the same communication configurations are set.
