Exchange 2010 OWA HTTP Error 500
Posted on 2011-09-22
I'm attempting to work through an issue with OWA on my new Exchange 2010 SP1 RU4 install. It looks like this is a known issue, but I can't find a working solution for me. My issue is that when we connect to OWA (internal or external), we can get to the login screen, then after that, we get an HTTP 500 error.
So, from what I've found and confirmed, is that the issue is with the Microsoft Forms Based Authentication Service. It doesn't star ton boot, and the service is set to delayed start. This is the case. If I attempt to manually start the service, it fails to start. From my event viewer:
Log Name: System
Source: Service Control Manager
Date: 9/22/2011 4:08:30 PM
Event ID: 7024
Task Category: None
The Microsoft Exchange Forms-Based Authentication service service terminated with service-specific error %%-2147467259.
The service shows no dependencies (is that correct?). But I cannot get the service to start for the life of me.
