That is a runtime error, right? You need to initialize windsock before using it. See, for example: http://msdn.microsoft.com/en-us/library/windows/desktop/ms738566(v=vs.85).aspx. There's documentation on runtime winsock errors here: http://msdn.microsoft.com/en-us/library/windows/desktop/ms740668(v=vs.85).aspx.
