MFC/ADO to VB/COM/ADO error

[JoshClark]

I'm working an MFC DLL that will be used in a VB white-box testing tool. My DLL references the ADO typelib to recognize types used in imported VB COM objects that are used as middleware between the application-under-test's web front-end and MSSQL back-end. I keep getting this one freaking error when I try to build my DLL:

Fatal Error C1189: Windows.h already included. MFC apps must not #include <windows.h>.

What is causing this and how can I fix it?

Urgent! Please Help!!
