Http Error: 503 the service is unavailable.. SharePoint System.ServiceModel

Ever had this?

I just did. This error found me just after I finished rolling one of our servers back onto the farm.. I will tell you how it came to not be on the farm a bit later *cough*

Symptoms:

Anyway, when I tried to navigate to the SharePoint Admin Site I got this error.. well trying to navigate anywhere on the server in SharePoint caused got me this error.

Diagnosis:

Something is wrong.. I will try the consult the mystical Event Viewer for guidance..

System.ServiceModel.ServiceHostingEnvironment+HostingManager/17653682System.ServiceModel.ServiceActivationException:
The service '/09c5aacd0f30411c96700fa84ffc0846/ProfilePropertyService.svc'
cannot be activated due to an exception during compilation. The exception message is: The farm is unavailable..
---> System.InvalidOperationException: The farm is unavailable. At blah blah blah..

Solution:

Pfff.. easy, I will just reset my Admin accounts for the services.. that should do the trick.

Well you should always check all the SharePoint Services and the username that runs them.. so make sure that password does not expire..
