In a remote desktop system, information pertaining to client resources is included in screen information that a server manages to display in a client. In the remote desktop system, the client collects information pertaining to units making up the client or to programs as resource information, and sends the collected information to the server via a network. The server manages the resource information obtained from the client, and creates screen information to be displayed in the client. In the creation of the screen information, the server creates client screen information (first screen) including the resource information of the server within the screen information of the client, or creates server screen information (second screen) including the resource information of the client within the screen information of the server, and displays the first or second screen in the client.
