In a server-based computing environment, an environment that is the same as the environment realized on a server is provided to a user at a place where connection to a network can not be established. A virtual computer is constructed on the server. A client can executes an application program on the virtual computer. When the client is disconnected from the network, data required for constructing the virtual computer are saved in a file and that file is sent as it is to the client. On the client, the received file is used to construct the virtual computer, and work is continued on the virtual computer.
