The Free On-line Dictionary of Computing (30 December 2018):

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.
