Help me with "fatal error C1189: #error : WINDOWS.H already included"

[bobby2387]

This line from the error seems pretty self-explanatory to me.

"MFC apps must not #include <windows.h>"

But I haven't used #include <windows.h>,except for the file server_main.cpp. When i am trying to remove the<windows.h> from that file I am getting the error as
