When application is configured to run using .NET Framework 4.5 and later, Iron Speed Designer uses Microsoft IIS Express as development server. . To make sure that your application is able to use Windows or Active Directory authentication please configure applicationhost.config file.
Step 1: Locate applicationhost.config file for the logged in user (note, that if multiple users log in to your machine you have to configure this file for each of them) at %userDir%\My Documents\IISExpress\config\ folder.
Step 2: Find <security> node in the file and modify two subnodes. Disable anonymous authentication (<anonymousAuthentication enabled="false" userName="" />) and enable windows authentication (<windowsAuthentication enabled="true">)
Save the file.
