I found some errors in DNN when working with child portals.

If we change default document in IIS to something else (eg. Index.aspx), and all child portals will broken.

Any solution on this ?

Thanks Brandon for your response, but the problem is Default.aspx and Index.aspx is separate page. In my case, Index.aspx is just welcome page to show everytime someone access my url. Index.aspx is just a welcome page, not a separate application.

I guess, it's about a code in core library when redirecting to DNN's domain without typing Default.aspx.

Any idea on this ?

Actually, index.aspx is not just splash screen. It's a fully page with some basic information (that's what my client need :(   ).

My DNN site is using 3 languages (bahasa, english, and japanese). And every time a user connect to the domain, it should shows an information page (not default.aspx) but other page with some information like :

... image header
.... English (click here), Bahasa (click here), Japanese (click here)
... footer header

And when client click on those link, it will redirects to appropriate page with it's language. If user do no action, then they only see index.aspx. That's the scenario.

User request --> index.aspx --> 1. English, http://domain/lang/en-us/default.aspx
                                                   --> 2. Bahasa, http://domain/lang/id-ID/default.aspx
                                                   --> 3. Japanese, http://domain/lang/ja-JP/default.aspx

Any idea on this ?
