DOS requester
     
         An {MS-DOS} {client} that provides transparent
        redirection of printing and file accesses to a network
        {server}.  It handles levels 3, 4 and 5 of the {Open Systems
        Interconnect} seven layer model.
     
        A DOS requester under {Novell NetWare} will interface to a
        {network card} driver with an {ODI} interface, and will be
        either a single executable (netx.exe) or a set of {VLM}s that
        are loaded on demand.
     
        In the {IBM}/{Microsoft} {LAN Manager}/{SMB} world, where
        the name {DOS redirector} is more common, there will be an
        {NDIS} interface driver and a net.exe executable.
