Abstract
When a first computer on a network is subjected to a shutdown operation, the first computer sends a power-off request to other computers on the network. If a second computer that has received this power-off request cannot be powered off, the second computer determines whether or not the power-off request is from a communication partner of the second computer. If the power-off request is not from a communication partner, the second computer remains powered on. If the power-off request is from a communication partner, the second computer returns to the communication partner a response indicating a refusal to accept the power-off request. If the communication partner receives the response indicating a refusal to accept the power-off request, the communication partner remains powered on. A computer that has sent a power-off request is powered off if it does not receive a response indicating a refusal to accept the power-off request.
