A system and method of managing products includes a server which is networked with a plurality of terminals to provide users of the terminals with proper support. When a support event occurs at any terminal, the terminal requests the server, through a requesting section, for support via a network, along with an IP address. The server, which includes a database containing registration information such as IP addresses and purchase dates registered when the terminals are purchased, receives the request including the IP address via a receiver, and searches for relevant registration information contained in the database in accordance with the IP address to provide the requested support.
