Installation on Windows Server 2008R2 not working (1 Viewer)

[ulischultz]

I installed WebMediaPortal according to this instructions:
http://wiki.team-mediaportal.com/1_..._Access/MPExtended/WebMediaPortal/IIS_Edition

When I want to load the website in a browser, the site keeps loading forever, without any error.
The MPExtended Service runs fine.

Is there any more detailed installation instruction?
Where can I find any logs, that might probably help?

Thanks for any help.
