Error when running a simple project...

When I run my simple project, I get the following error and nothing is displayed on IE.

What to do?

Thanks.

What web server are you using?

Windows XP Pro's IIS.

Thanks.

I think, the problem might be that you havent installed all the prerequisites that are required for .net.
What you could do is run your VS.NET setup disk and it will tell you what is missing.
