From the Win32 API documentation:


    Network subsystem is unavailable.

    This error is returned by WSAStartup if the Windows Sockets
implementation cannot function at this time because the underlying system it
uses to provide network services is currently unavailable. Users should

    - that the appropriate Windows Sockets DLL file is in the current path,

    - that they are not trying to use more than one Windows Sockets
implementation simultaneously. If there is more than one WINSOCK DLL on your
system, be sure the first one in the path is appropriate for the network
subsystem currently loaded.

    - the Windows Sockets implementation documentation to be sure all
necessary components are currently installed and configured correctly.
