How to implement Windows Authentication

Hi Friends,

Please suggest me how to implement windows authentication for my application. My application has three pages.

1. Home. aspx

2. Admi/Home.aspx

3. User/Home.aspx

I don't want to authenticate home.aspx page. but remaining two pages i want to authenticate through windows user. how do i implement.

My code.

I wrote code in web.config in root directory:

<authentication mode="windows" />

<authorization>

<deny users="?"/>

<authorization>
