Microsoft Networking
     
         {Microsoft's} name for the networking subsystems
        of {Windows 95} and later.  Not to be confused with {The
        Microsoft Network}.
     
        Microsoft networking uses the {SMB} file sharing protocol.  It
        is implemented as file system drivers i.e. "{installable file
        systems}" (IFS).
     
        The {network redirector} "Client for Microsoft Networks", is
        implemented in the VREDIR.VXD {virtual device driver}.  {Peer}
        resource sharing is provided by "File and Printer Sharing for
        Microsoft Networks" (VSERVER.VXD).
     
        Windows 95's support for {Netware} ({NCP}) networks is
        provided in a similar way via NWREDIR.VXD and NWSERVER.VXD.
