Hi
I want to debug an application on local machine
i just write simple asp application
but debug don't start

When I debug an ASP.NET application in Visual Studio .NET, i receive the
following error message:

Error while trying to run project: Unable to start debugging on the web
server. Access is denied. Would you like to disable future attempts to debug
ASP.NET pages for this project?

- I'm administrator, and i belog to user debugging group
- IIS installed OK
- aspnet_wp installed correctly
