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.
