Hi Karl,
Thanks for reaching out to the forums on this issue. My name is Josh Wells and I am a support engineer on the Microsoft Dynamics CRM support team.
I have reviewed your issue and I see you are having issues accessing the Organization service. What is the Web Address you have configured within the Deployment Manager when you right-click on Microsoft Dynamics CRM then Properties?
Also have you tried using a tool like Fiddler to see what may be happening as well? Fiddler is a web debugging tool that will allow you to monitor web requests and corresponding failures. You may get a better exception within the Fiddler trace than the exception you are currently seeing. You can find Fiddler here:
Additionally, I would verify that the web service request is actually making it to the CRM server by looking at the IIS logs for the CRM website. This would confirm that the requests are making it to the server and log what the HTTP response is.
Lastly, if you have confirmed the request is making it to the CRM website, you can enable CRM platform tracing to see if there are additional errors being logged there:

Hope this helps. If you have any questions, please let us know.
