when i move a copy of my dnn proj from development machine to UAT machine, the dnn proj keep redirecting to the default page. msg showing in IE status bar as: web site found, please wait for reply.  you can see the status bar is blinking ...   firefox will tell u that that is infinite redirecting to the same page. IIS server will never display a err msg.

after some research, i realized quite some people has the same problem and there was no solution.

and after some troubleshoot, i found the problem could be due to
<trust level="Medium" originUrl=".*" />

i enabled this setting when i deployed the proj to a moss server for testing.

after I comment this line in the web.config, everything comes back to normal. Dont have time for further troubleshooting, but i help this post can help you a little bit. I stuck here for almost one whole day.

The problem is when your home page is disabled, DNN redirect to the portal alias address.

Example:
1. http://www.mysite.com/myalias
2. redirect to http://www.mysite.com/default.aspx?alias=http://www.mysite.com/myalias
3. try to redirect to site home page but DNN find a  page disabled then redirect to http://www.mysite.com/myalias

Thus, if you activate the page, it works fine. This action is made in Default.aspx.vb in page init procedure.

Look how you can reproduce the bug:

In site settings, Splash page in undefined.

The site home page defined (or undefined but the home page is the first page of the site)

In the site home page settings, set Disabled on.

Logout and you will see the result.

If you want to go back to change it, just log in into another site with host user and reenter into your web site.
