Abstract: An automatic address distributing method, computer program and system for automatically examining addresses already assigned to terminals connected to a network without regard to the status of the existing terminals and removed terminals. An address may be assigned to a terminal by apparatus other than a DHCP server. After a Dynamic Host Configuration Protocol (DHCP) server has been started, addresses currently used in a network are examined by a duplicate-address examining unit and the status of the address are stored in an in-use-address database (DB). When a terminal makes a request for distribution of an address, the DHCP server distributes an address that is currently not used in the network. In the examination carried out by the duplicate-address examining unit, an inquiry about the entire name information controlled by a Domain Name Service (DNS) server is made to the DNS server. Results of the inquiry are also stored in the in-use-address DB. Then, a mobile-agent DB is examined for a mobile agent.

Abstract: A client server system has clients, a server of execution system, and a server of fault auxiliary system are connected. A process administrator is provided in each one of the server of execution system and the server of fault auxiliary system. When a fault has occurred in a disk processor in the server of execution system, the process administrator in the server of execution system transmits only "requests" relating to the disk processor among "requests" received from clients to the server of fault auxiliary system. A process administrator in the server of fault auxiliary system conducts corresponding server processing on the "requests" transmitted from the server of execution system.
