SBS 2011 and Exchange Management Console not working

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 127.0.0.1:80 (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?

Also, I noticed another error, under the Default Web Site section of IIS, it lists the 4 web applications; however all give the same error when i try to connect to them internally.
1. Browse 127.0.0.1:80 (http)
2. Browse *.80 (http)
3. Browse *.443 (https)
4. Browse 127.0.0.1:443 (https)

"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"

These are the sites currently listed in IIS

1. Companyweb: port 80 (works fine when i click on it in IIS and brings me to Internal Web Site)

2. Default Web Site (all of which prompt me with the error ""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" whenever I click on it)

Browse 127.0.0.1:80 (http)   /    Browse *.80 (http)   /   Browse *.443 (https)   /   Browse 127.0.0.1:443 (https)

3. SBS Client Deployment Applications: Port 80

4.  SBS Sharepoint:  Port 987

5. Sharepoint Central Administration: Port 24682

6. Sharepoint Web Services: Port 32843 (http) AND Port 32884 (https)  (Both site links give error: " HTTP Error 503. The service is unavailable.)

7. WSUS Administration: Port 8530 (http) AND Port 8531 (https)  (Gives error: HTTP Error 403.14 - Forbidden The Web server is configured to not list the contents of this directory."


Looking over this, I see 4 instances where port 80 is used, but not sure which ones should be using that port.  Do you think this could be the root cause of my problem and can simply remove the incorrect web app from IIS, etc to fix it? Thanks again for any help in advance
