    Re: Error code : 0x80070021 and HTTP Error 500.19

     This is what worked for me:

    Windows Server 2012, IIS 8.5. Should work for other versions too.

    1.Go to server manager, click add roles and features
    2.In the roles section choose: Web Server
           a. Under Security sub-section choose everything (I excluded digest, IP restrictions and URL authorization as we don't use them)
           b. Under Application Development choose .NET Extensibility 4.5, ASP>NET 4.5, both ISAPI entries
    3. In the features section choose: NET 3.5, .NET 4.5, ASP.NET 4.5
    4. In the web server section choose: Web Server (all), Management Tools (IIS Management Console and Management Service), Windows Authentication - if you are using any of it
