Abstract: A network server (14) permits clients (11) on the network to access one or more local resources managed by the network server and one or more remote resources managed by one or more respective remote computers coupled to the network server. When a client desires to access any of the resources, the client first requests a session or log-on to the network server by supplying a valid account name and password. Either with the session establishment request or subsequently during the same session, the client requests a connection or access to a resource. The client need not know the location of the resource or the computer (remote or network server) which manages the resource. The network server determines which computer manages the requested resource. If the network server manages the resource, then the network server determines if the connection is available or provides the access as requested and responds to the client. Then, if the client subsequently requests a connection with or access to a resource managed by a remote computer, or if the original request was for a resource managed by the remote computer, the network server sends a session establishment request and connect or access request to the remote computer. The client need not send a separate session establishment request for the remote computer. If the remote computer grants the session, then the client can access the resource managed by the remote computer.
