PURPOSE:To accurately execute the same processing again at the time of the occurrence of operation error in the computer system where the distributed processing is performed by computers connected to a transmission line. CONSTITUTION:Respective functions of a message read means 19 which reads each message outputted to the transmission line in the information processing stage of each computer, a communication history storage means 18 where successively read messages are stored in time series together with message occurrence time information, and a message reproducing means 20 which successively outputs stored messages at intervals of time indicated by occurrence time information in response to a re-execution command of information processing are added to a LAN monitor device 13 connected to the transmission line 11. Computers 12a to 12c execute the information processing again in response to the re-execution command and inhibit the message output to the transmission line 11 during re-execution.
