How do I incorporate aspx pages with Dreamweaver?

I created my web page with Dreamweaver CS3; and this week I set up a login page, registration page, etc. I did the second part with Visual Studio 2005 web application and ASP.NET . So that is done.

Now my question is how do I incorporate aspx pages(registration,login,) with my Dreamweaver web site?

I thought maybe I would have to move the whole VS folder into the Inetpub->wwwroot folder? And then maybe open up dreamweaver and link the pages. But that is a hypothetical guess.

What I am wanting to do is when a person comes to my page; they will see the first page(which is the index page), and then when they click enter(which is currently set to go straight to video page); I want it to lead them to the login page.
