An information-processing system processes set-up identification information, which specifies a set-up item that is an adjustment attribute of a predetermined function of an electronic apparatus connectable to a network. The electronic apparatus that sets a parameter and the electronic apparatus on which the parameter is set are connected to each other. The electronic apparatus on which the parameter is set receives the set-up identification information from the electronic apparatus that sets the parameter. It also analyzes the set-up identification information thus received and converts the set-up identification information thus analyzed into set-up identification information of the electronic apparatus on which the parameter is set. It further changes a parameter setting of the electronic apparatus on which the parameter is set on the basis of adjustment contents of the set-up item correlated with the set-up identification information thus converted.
