Hi @Mohamed Ahmed

The 404.3 error should be caused by missing components in your IIS, you should install IIS sub components from:

Control Panel -> Programs and Features -> Turn Windows features on or off

Internet Information Services has subsection World Wide Web Services / Application Development Features

There you must check ASP.NET (.NET Extensibility, ISAPI Extensions, ISAPI Filters will be selected automatically). Double check that specific versions are checked.

Hi @Mohamed Ahmed ,

did you configure the default document for the website?

I don't know if the default document of your web-app is Default.aspx or LoginUser.aspx .
