Hi, I'm using Visual Studio 2008 SP1, and SQL Server 2005 for educational purposes.
I'm working in few diferent projects ang jumping from one to another.
Now I run into following problem, and after few hours I got some conclusions but not solved the problem entirely.

PROBLEM : When I open existing Web Sites in Visual Studio (or create a new one! ) and try to run any page, in firefox the page remains silver, and in IE I get the message : Internet Explorer cannot display the web page.
BUT, when I open a PROJECT, or create a new project and ASP.NET WebAplication, everything works fine.
As I needed the solution to continue developing a web site started earlier, I just created a new project and added existing files an folders and now I can use them.

I understand that there must be some problem in how the web site project starts the virtual server, but I'm not sure where is the problem.
