Hi Sourabh, The "Error 500.19 - Internal Server Error" in IIS indicates that there is an issue with the configuration of your application or the server. This error often occurs due to problems with the web.config file or permissions. Here are some common causes and solutions to help you troubleshoot the issue: Common Causes and Solutions Invalid Configuration in web.config: Check the web.config file for any syntax errors or invalid settings. Look for unclosed tags, incorrect attributes, or misplaced elements. Ensure that all required sections are properly defined. Missing or Incorrect Modules: Ensure that the necessary modules are installed and enabled in IIS. For example, if you are using ASP.NET MVC, make sure that the ASP.NET feature is enabled in your IIS installation. You can check this in the "Modules" feature of your site in IIS Manager. File Permissions: Ensure that the application pool identity has the necessary permissions to access the application's folder. Typically, the application pool identity is IIS AppPool\ . Right-click on your application folder, go to "Properties" -> "Security" tab, and make sure the application pool identity has at least read access. Application Pool Configuration: Verify that the application pool is set to use the correct version of the .NET Framework. If your application is targeting .NET Framework 4.x, ensure that the application pool is set to use "No Managed Code" for .NET Core applications or the appropriate .NET Framework version for ASP.NET applications. Check the Event Viewer: Look at the Windows Event Viewer for more detailed error messages. This can provide additional context about what might be going wrong. Detailed Error Messages: To get more detailed error messages instead of the generic 500.19 error, you can modify your web.config to allow detailed error messages. Add the following within the section: Ensure the Correct Site is Selected: Make sure you are accessing the correct site in IIS. Sometimes, multiple sites may be running, and you might be looking at the wrong one. Check for Duplicate Configuration Sections: Ensure that there are no duplicate sections in your web.config file or in any parent configuration files (like applicationHost.config).

To fix HTTP Error 500.19 on IIS for your MVC project, ensure that ASP.NET features are enabled in Windows Features (including .NET Extensibility and ASP.NET), check that the application pool in IIS is set to the correct .NET CLR version in Integrated mode, and confirm that IIS_IUSRS has read permissions on your project folder. Then restart IIS to apply the changes.
