IIS 8.0 ASP.NET and Error 500.19


ASP.Net applications come pre-wired with a handlers section in the web.config.

By default, this is set to readonly within feature delegation within IIS.

Take a look in IIS Manager, under the Server nameFeature delegation. If Handler Mappings is set to readonly and your site web.configs have a handlers section, flip the value to read/write and see what happens.

Worked for me when moving to Windows 8 / IIS 8 / ASP.Net MVC 4.


  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. I checked all but not CGI.

i'm using w10 technical preview


I had same issue, this is because the app pool doesn't have rights to the web site directory or web.config. Try to grant rights for "IIS_IUSRS" with : Read,Execute,List.
