Management system and information processing method

A management system with a management agent program installed and communicable with a first information processing apparatus registered as a management agent via a network, the management system comprising:

• a first reception unit configured to receive, from the first information processing apparatus, communication information of a network device which failed in communication for monitoring with the first information processing apparatus among network devices as management targets of the first information processing apparatus;
• a control unit configured to perform control to register a second information processing apparatus as a management agent to perform the communication for monitoring with the network device corresponding to the received communication information;
• a transmission unit configured to transmit to the second information processing apparatus an installer which includes a setting of prohibiting installation to a device not existing in a network segment to which the network device corresponding to the received communication information belongs;
• and
• a change unit configured to change a search range so as to delete the network segment to which the network device corresponding to the received communication information belongs from the search range set with respect to the first information processing apparatus,
• wherein, in a case where the transmitted installer is executed in the second information processing apparatus existing in the network segment to which the network device corresponding to the received communication information belongs, a management agent program for managing the network device corresponding to the received communication information is installed in the second information processing apparatus.
