Visual Studio debugger does not attach when at the root of the site

I had a problem with my Visual Studio 2008 debugger, not related to the root of the default website when I start from the environment.

I have a .NET 3.5 web application project running on VS 2008 SP1. I set the project to "Use the local IIS web server" with the outline " http: // localhost / ". I can create a virtual directory and the application compiles fine.

My problem is that when IE starts the debugger, it is not connected. I can "Attach to the process" and select "w3wp.exe", and it will debug just fine. This is PITA, and I was curious if anyone knows why this will not be automatically attached?

I used this exact project under VD and never had a problem with lack of debugging. Thoughts?

The problem I ran into is that I had a tag in my web.config that surrounded my tag. This obviously causes the debugger to attach, and then immediately throw an error without any warnings or errors. Here is an article I used to figure this out:

I would try to start VS using an administrator account.
