Unable to connect to Exchange Management Shell - Excahnge 2010 Hosted mode

My client has an Exchange 2010 server running in hosted mode and therefore aonly accessible via the Exchange Management Shell. All was working fine until about 2 weeks ago.

Now when the client runs up the Exchange Management Shell they get:
RMClient Error
As text:
VERBOSE: Connecting to server.domain.forest.ads
[server.domain.forest.ads] Connecting to remote server failed with the following error message : The WinRM client cannot complete the operation with

    + CategoryInfo          : OpenError: (System.Manageme....RemoteRunspace:RemoteRunspace) [], PSRemotingTransportException
    + FullyQualifiedErrorId : PSSessionOpenFailed

No change has been made on the server. No updates. Nothing.

We have tried restarting the Exchange services, rebooting the server.

Any ideas?
Thanks

Finally!!!

Following the advice here https://social.technet.microsoft.com/Forums/en-US/641e0691-8f27-4f5a-a895-07b8e97d7e6d/lync-2010-application-pools-wont-start?forum=ocsplanningdeployment I managed to remove the errors from the event log that I had mentioned above and now the EMS is connecting fine.

Thanks

Is the WWW Publishing Service started on the server? Anything in Event Viewer?

Making Bulk Changes to Active Directory

Watch this video to see how easy it is to make mass changes to Active Directory from an external text file without using complicated scripts.

The last screenshot would be where I would start. If there is a problem with the Exchange PowerShell Virtual Directory in IIS, this is likely the root cause. Ran across this - http://kb.prismmicrosys.com/evtpass/evtpages/EventId_5139_Microsoft-Windows-WAS_64841.asp

Might be easier to just bounce the server. When was the last restart?

Also, I have just followed the step by step in that article and get the same result in the EMS.

Still working on this. We are upgrading the RAM in the server over the coming weeks from 6GB to 38GB. I'm hoping that this change and a full reboot will bring back the EMS to being able to connect to the server.

Thanks
