Hello, Peter.
Thank you for using UltiDev products.
We'll do our best to help you troubleshooting this one out. You seem to have registered your app's physical location folder correctly, but default document set to "Src\Default.aspx" might be a cleaner approach.
We suspect that when you launch the app, the incorrect default document is requested, but preempted by login page. To verify whether it's a correct theory please see whether the URL in the address bar of the browser looks something like login.aspx?
ReturnUrl=%2fDefault.aspx. If so, then DestinationPageUrl setting in web.config does not play any role and after logging in you get redirected to the original default document location that was probably incorrect in the first place.
Please let us know if this information has helped.
Best regards,
UltiDev Team.
