    If you are using that compiler, then use the most up to date header and lib....

    Add the ws2_32.lib to the library and use winsock2.h

    If you use winsock2.h, you dont need windows.h...

    Best bet, remove includes for windows.h & winsock.h and replace with these 2 lines

    Code:
    #include <winsock2.h>
    #pragma comment(lib,"ws2_32.lib")
