Unable to browse When IIS Publishing Service, prompting mime Registration

Problem description:

Error Summary
HTTP 404.3-not found
The page you requested cannot be provided due to scaling configuration issues. If the page is a script, add it for processing.Program. If you want to download the file, add the mime ing.
The most likely cause is:
The handler ing may be missing. By default, the static file handler processes all content.
The feature you want to use may not be installed yet.
No mime ing is enabled for the website or application. (Warning: do not create mime ing for content such as the. SVC. ASPX page or. config file that the user should not download .)
If ASP. NET is not installed.
What I met today is that Asp.net is not registered in IIS.

Solution
Find the vs2010 command prompt tool, the vs 2008 command prompt tool, or the vs2005 command prompt tool. Run the command as administrator.
