EMC and EMS won't load

After applying the latest available updates to my Exchange 2010 server (all roles on the same server), I experienced many problems with all Exchange services.  Finally got everything working after applying SP3 and Rollup 2.  However, I still can't access EMC or EMS.  I've tried every fix posted on the net, including the Kerberos settings, authentication settings, removing/creating the Powershell virtual directory, etc.  OWA and Activesync appear to be working well.  The problem I am having is related to the powershell assembly microsoft.exchange.configuration.redirectionmodule, which won't load.  Note that I have checked redirection on the default website and redirection is NOT enabled.  Also, SSL is NOT enabled on the powershell virtual directory.

Note that all references to the server name have been changed for security purposes.

The error I get from the EMC is:
Connecting to remove 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.  It was running the command 'Discover-ExchangeServer -UseWIA $true -SuppressError $true -CurrentVersion 'Version 14.3 (Build 123.4)"

When I try to browse to the path http:\\localhost\powershell I get this error:

PLEASE note that I have been through every blog post, KB article, and anything else I can find and nothing has worked.  I'm hoping someone can come up with a new approach.

Thanks!!
