Hello, we are currently getting an error with EMC on our SBS 2011 server.  It was working fine for a couple of weeks and is not having issues opening up.  The error I am getting when I try to open up EMC is:  "The attempt to connect to https://server.local/powershell using "kerebros" authentication failed:  Connecting to the remote server failed with the following error message - "The WinRM client cannot process the request. It cannot determine the content type of the https response from the destination computer."

After checking the application logs, I see 2 IIS errors:
1.   Event ID 2214: The HTTP Filter DLL C:\Program Files\Microsoft\Exchange Server\V14\ClientAccess\owa\auth\owaauth.dll failed to load.  The data is the error.
2.  Event ID 2268:  Could not load all ISAPI filters for site 'DEFAULT WEB SITE'.  Therefore site startup aborted.

I'm thinking it might have something to do with IIS, but am not quite sure.  When I open up IIS manager under the Default Web Site Application Pool, I noticed that there are 2 Web Sites listed under port 80 (again, not sure if this is causing the issue).  When I click on both, I get the "HTTP Error 500.0 - Internal Server Error
Calling LoadLibraryEx on ISAPI filter "C:\Program Files\Microsoft\Exchange Server\V14\ClientAccess\owa\auth\owaauth.dll" failed" error.     The sites listed are:
1. Browse (http)
2. Browse *:80 (http)

Does anyone know how and whether or not IIS is indeed the culprit here? If so, any easy way to fix it accordingly?
