What are you saying? Is there a question in there somewhere?

Obviously, I want my site to connect to a database. This database contains the addresses of other sites. The website address to check whether the websites are down or not.
What I want and it is important to me: Must identify why the website is down (find problem)

You will have to make a webrequest to each site and interpret the response code:

How that I use in asp.net 3.5

You have to create a webrequest object, and make the request. There are many, many examples on line. Then you get the response back, you put that into a response object. From there you can read the response code and then interpret that from the link I sent you.
