Hallo all

I upgraded dnn 5.4.2 to 05.04.04 (2)  and that part went well.
The version runs on its own app pool IIS6 server 2003
Now I changed asp.net version 2.0.50727 to asp.net version 4.0.30319 in IIS ASP.NET tab. After a while de site comes back with:

Server Error in '/' Application.
--------------------------------------------------------------------------------

The resource cannot be found.
Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable.  Please review the following URL and make sure that it is spelled correctly.

Requested URL: /

--------------------------------------------------------------------------------
Version Information: Microsoft .NET Framework Version:4.0.30319; ASP.NET Version:4.0.30319.1

As you can see the Requested URL is enpty.
when I enter the Url http://www.mysite.com/default.aspx then the is comes up

Any suggestion welcome
