I have a SBS 2011. Suddenly we cannot start the EMC. It gives the following error nmessage: Connecting to remote server failed with the following error message: The WinRM client cannot process the request. It cannot determine the content type of the HTTP response from the destination computer. The content type is absent or invalid. For more information, see the about_Remote_Troubleshooting Help topic.
I have found a lot on information about this problem on Internet and I have checked/tried/changed everything but no luck.
Anyone who can guide me through a step by step fault finding?
