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.

Abstract: A computer system manages files shared by first and second heterogeneous clients. The first client exhibits a first protocol such as SMB and the second client exhibits a second, different protocol such as NFS. The system comprises a first protocol converter which receives requests from the first client to create, read and update the files, and converts the requests to corresponding requests exhibiting a common protocol. The system also comprises a second protocol converter which receives requests from the second client to create, read and update the files, and converts the requests to corresponding requests exhibiting the common protocol. The system also comprises a file manager common to both clients and both protocol converters, which receives the converted requests exhibiting the common protocol and executes the requests in a name space and data area which are both common to the first and second clients. The name space stores names of the files and the data area stores the files. The file manager provides access by each of the clients to files and names of the files created by the other client. The system further comprises a common lock manager for the common name space and common data area. The system also supports second and third name spaces and data areas dedicated to the first and second clients, respectively.

Abstract: A network server permits clients 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.
