PROBLEM TO BE SOLVED: To reduce the time for unnecessary access processing to a server device which is not connectable due to maintenance. SOLUTION: In the server client system including a plurality of server devices each of which has a communicating state of connected or non-connected state with a communication network, and at least one client terminal which accesses the server devices through the communication network, and the communicating state delivery server therefor, a detection signal is intermittently transmitted to each of the server devices, when an answer signal is received therefrom, the communicating state with the server device concerned is determined to be a connected state, and a communicating state list showing the communicating state determined for each of the plurality of server devices is delivered to each client terminal. Each client terminal stops, when the communicating state of the server device that is its own access object is the unconnected state in the delivered communicating state list, the access thereto.
