Abstract
Configuration information representing the configuration elements of a client PC or the like on a network is compared with initial configuration information. When the configuration information changes, it is determined whether the configuration is proper. If the configuration is improper, the function of a corresponding configuration element to the network is inhibited. This can prevent an unstable state of the system, leakage of information, and a decrease in reliability of the network system upon a change in network configuration.
