Including .lib and headers into project causes C1189 windows.h already included error

Hi,

I have written a Win32 console app in visual studio 2003 .net which uses sockets therefore includes winsock2.h and the wsock32.lib.

I now have to incorporate some files that someone else has written and also include a .lib and some headers in my project's setting in order for their code to work. The headers for their code that I have added to stdafx.h are called ModuleIo.h and ApplicatioIo.h. These headers include a lot of other headers that are in the directory that I have added to the include directories in the project settings. But none of these includes are windows headers - they are all provided by someone and have more of their code in.

The trouble is I now get the "C1189 windows.h already defined" problem. I have read so much about this on the internet but I still can't find a solution to my problem. I will post my stdafx.h here, but the problem does not occur until I incorporate somebody elses code and .libs. Everyone else seems to solve this by reordering their #includes in stdafx.h but I have tried that (putting winsock2.h at the start or end) but it makes no difference.

// stdafx.h : 
#pragma once
#include <winsock2.h>
#include <stdio.h>
#include <tchar.h>
#include <process.h> //for _beginThread
#include <iostream>
#include <stdlib.h>
#include <conio.h> //for getche()
#include <errno.h>
#include <time.h>
#include <string>
#include <sstream>
#include <stddef.h>
#include <atlbase.h> //for debug TRACE
#include <signal.h>
#include "DigiConfig.h"
#include "CardStatus.h"//for the enums E_RAD2_STATES
#include "CardBulkXfer.h"
#include "SharedMemory.h"
#include "CardInterface.h"
#include "ModuleIo.h"// this is an added header
#include "ApplicationIo.h"// this is an added header
#include "CardCtrl.h"
#include "CardThread.h"
#include "ClientHandlerThread.h"
#include "ConsoleHandler.h"
#include "CardDataWriterThread.h"
#include "CardDataHandlerThread.h"

I did try putting #undef _WINDOWS_ after the #include "winsock2.h", which remove dthe error but produced a new one about an amiguous call to Sleep - which is defined in winbase.h and atlbase.h, so I am still including two defintions of methods which i shouldn't be and I really don't know what to try next. Please help!
