When I try to open an ASP.NET file on my computer the web server donít process
it and only return the asp.net file as it was writing. Even when I try to
debug an asp.net page in VS.NET I get problem. I get following message:

ďError while trying to run project: Unable to start debugging on the web
server. The server does not support debugging of ASP.NET or ATL Server applications.
Run setup to install the Visual Studio .NET server components. If setup has
been run verify that a valid URL has been specified.

You may also want to refer to the ASP.NET and ATL Server debugging topic
in the online documentation. Would you like to disable future attempts to
debug ASP.NET pages for this project?Ē

If I disable the debug, the result is as before, the page is not processed
by the web server.

I have tried to reinstall both IIS and VS.NET, but it doesnít help.
