If your custom ServiceHostFactory fails on Windows Server 2012 and IIS 8.5, there could be several reasons for the issue. Below are some common causes and troubleshooting steps to help you resolve the problem:

  1. IIS Configuration: Ensure that your IIS configuration is set up correctly to host your custom service. Double-check the application pool settings, .NET framework version, and other relevant configurations.

  2. Permissions: Check the permissions for the application folder and ensure that the user running the IIS application pool has the necessary permissions to access the files and resources required by your custom service.

  3. Event Logs: Check the Windows Event Viewer for any related error messages or exceptions that might provide more information about the cause of the failure.

  4. Custom Service Code: Review your custom ServiceHostFactory implementation for any issues or errors that could cause it to fail on Windows Server 2012 and IIS 8.5. Double-check the code for any compatibility issues with the .NET framework version running on the server.

  5. .NET Framework Version: Verify that the correct version of the .NET Framework is installed on the server. Ensure that your custom service is compatible with the .NET Framework version installed on Windows Server 2012.

  6. Application Pool Identity: Check the identity under which the IIS application pool is running. If your custom service requires specific user permissions or access to external resources, ensure that the application pool identity has the necessary privileges.

  7. Isolation Mode: If your custom service requires a specific application pool isolation mode (e.g., Integrated or Classic), make sure it is set correctly in the IIS configuration.

  8. Debugging: If possible, enable detailed error messages and remote debugging on the server to get more information about the failure.

  9. Test on a Different Environment: Try running your custom service on a different environment with similar specifications (e.g., another Windows Server 2012 machine with IIS 8.5) to see if the issue is specific to the current server or configuration.

  10. Check Dependencies: Ensure that any external dependencies required by your custom service (e.g., third-party libraries) are correctly installed and accessible on the server.

By thoroughly investigating these potential causes, you should be able to identify and resolve the issue with your custom ServiceHostFactory failing on Windows Server 2012 and IIS 8.5. If the problem persists, consider seeking help from your development team or consulting with IIS and .NET experts for further assistance.
