When a server has to deal with lots of short lived client connections, it's advisable to use the Microsoft extension function for WinSock, AcceptEx(), to accept connections.
// ServerShutdown.cpp : Defines the class behaviors for the application.
//

#include "stdafx.h"
#include "ServerShutdown.h"
#include "ServerShutdownDlg.h"

#ifdef _DEBUG
#define new DEBUG_NEW
#undef THIS_FILE
static char THIS_FILE[] = __FILE__;
#endif
