PPROBLEM TO BE SOLVED: To provide a server for storing maintenance/diagnostic data, a system for storing/acquiring maintenance/diagnostic data and a system for storing/presenting the maintenance/diagnostic data to be used for executing the maintenance/diagnosis of the device in a remote place capable of maintaining security in the same way as executing the maintenance/diagnosis of the device not in a remote place. PSOLUTION: Maintenance/diagnostic data associated with a device are stored, and a data access request transmitted through a first network and a first fire wall is detected, and user authentication is requested through a second fire wall whose security level is higher than that of the first fire wall and a second network to the device based on the detected data access request. Then, the result of the user authentication is acquired through the second network and the second fire wall, and the maintenance/diagnostic data stored based on the data access request are outputted through the first fire wall to the first network.
