<P>PROBLEM TO BE SOLVED: To quickly detect that a client computer fails by reducing the load of a server computer or a network load near the server computer. Ž<P>SOLUTION: In this computer system, a first callback processing part 161a transmits an alive notification packet including an address of the client computer 10a at a time interval T1. A client reception packet processing part 14b stores a record including the address included in the transmitted alive notification packet and a receiving time when the alive notification packet is received in a client connection state table 15b. A second callback processing part 162b acquires a record in which a difference between the current time and the receiving time is larger than a time interval T2 from the client connection state table 15b at the time interval T2. The second callback processing part 162b notifies the server computer 20 that the client computer 10a fails to which an address included in the acquired record is allocated.
