503: Service unavailable

Hi!

I installed Aras Innovator 9.4.0 on our newly installed Windows Server 2008 R2 Datacenter.

I followed the instructions from this video:

http://www.youtube.com/watch?v=osLK5k2_Zxs

and installed all prerequisites mentioned in the video.

When I open the url: http://localhost/InnovatorServer on the server I get the error:

HTTP Error 503. The service is unavailable.

How can I fix this?

Thanks for the help!

There are also some events logged in the event viewer:

(Translated from german):

Event ID: 2276, The worker processfailed to initializecorrectlyandtherefore could notbe started

Event ID: 5009, A process serving applicationpool '"ArasASP.NET 4.0AppPool""has unexpectedly quit.The process IDis "278896".Theprocess exitcode is "0xfffffffe"

I attached the full event log (it should also contain english error messages).
