The WinRM client cannot process the request. It cannot determine the content type of the HTTP response from the destination computer.

Hi,

I'm getting the following error when I try to launch the Exchange Management Shell.

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.

The server resolves fine, I tried following this http://exchangeserverpro.com/the-winrm-shell-client-cannot-process-the-request/ and re do all the bindings in the Default web site (with iisreset) but no success.

I tried with the domain admin user but same problem. A reboot of the server didn't help either.

I also tried to access the server with ECP but it didn't work. I can't do anything else before resolving this issue. I managed to find a powershell script to troubleshoot this problem but it requires to be connected to the Exchange server so I'm stuck.
