Answer 1

You can clearly find the cause of the error based on its error message, and you can find the error code in the official documentation, and you can try the solutions, please refer to the Scenario 7 in this document.

There are usually a few more lines in that error response that points to the exact line in the config file (and hence the locked section) that has the problem. You will either have to unlock that section or not use it in your application’s web.config file.

Or manually change value from "Deny" to "Allow" for below settings in %windir%\system32\inetsrv\config\applicationHost.config

Another way is checking your windows features.

1. Click "Start button"
2. in the search box, enter "Turn windows features on or off"
3. in the features window, Click: "Internet Information Services"
4. Click: "World Wide Web Services"
5. Click: "Application Development Features"
6. Check (enable) the features. Check all options but CGI.
