Help w/ localhost?

I am experiencing something very strange. When trying to debug on my local computer, I would get this message:
"The page cannot be displayed
The page you are looking for is currently unavailable. The Web site might be experiencing technical difficulties, or you may need to adjust your browser settings.
..............

This never happened to me before. It is now unpredictable. I am getting it before the page ever gets loaded, or upon clicking some button. In the past, when I had this message while trying to visit websites on the Internet, I thought the site was actually having some issues, or at least the connection was bad. But this is my own localhost and my own program?????????

Any help is greatly appreciated!

I have one more problem: why does my local web server keep stopping on me? I have two computers, both are running Windows 2000 server. One of them always starts IIS automatically, but the other has to be manually started. Worse yet, it keeps stopping by itself now. Could anyone tell me how to make it start automatically and stay running?

Thank you in advance.
