SUPPORT Q&A - 503: Service unavailable

Pro - Wednesday, August 7, 2013 7:44 AM:

Hi!

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

I followed the instructions from this video:

www.youtube.com/watch

and installed all prerequisites mentioned in the video.

When I open the url: 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 process failed to initialize correctly and therefore could not be started

Event ID: 5009, A process serving application pool '"Aras ASP.NET 4.0 AppPool" "has unexpectedly quit. The process ID is "278896". The process exit code is "0xfffffffe"

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

Hi Pro,

The 503 error you referenced ties to the improper setup of IIS. This is slightly different for each version.

Please ensure that at a minimum you have the following installed with the IIS role:

*ASP.NET

*ASP

*Windows Authentication

Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4

Please also ensure you have Microsoft .NET 4.0 installed.

Best,

Jennifer

Nice!!

Thanks a lot!

Installing .NET 4.0 fixed the problem (i had 3.5 installed as mentioned in the install guide).
