Unable to find ahadmin.h file

I am using Windows 64开发者_开发问答 bit machine (windows server 2008) & have IIS 7.5. When I try to build one of project which is in C++, it shows ahadmin.h file missing.

I am very new to IIS server project.

You need to download and install Windows SDK. It doesn't seems like this file comes with Visual Studio, but it's part of the SDK.
