HELP needed for OWA Access

Hi all, I need some help. My OWA exchange access is not working anymore. When users goto the site they get the following:

HTTP/1.1 200 OK
Server: Microsoft-IIS/7.5
Date: Mon, 14 Sep 2015 04:07:15 GMT
Connection: close

This is an SBS2011, Exchange 2010. This used to work until today. I did some sharepoint work, but did not think there was any correlation between sharepoint and Outlook Web Access. Perhaps these are just coincidental errors but included just in case...

I also see this in the event log

og Name:      Application
Source:        Microsoft-SharePoint Products-SharePoint Foundation
Date:          9/13/2015 5:55:04 PM
Event ID:      8059
Task Category: Configuration
Level:         Warning
User:          DOMAINNAME\spfarm
Computer:      SERVERNAME.DOMAINNAME.local
Alternate access mappings have not been configured.  Users or services are accessing the site http://SERVERNAME with the URL  This may cause incorrect links to be stored or returned to users.  If this is expected, add the URL as an AAM response URL.  

Any help is appreciated...

IIS can be complicated so I have shared some similar frustrations over time. Usually these errors are really spelling out what needs to be done. Run the Best Practices Analyzer (BPA) on your exchange server as well as the IIS server, through the server manager.

The BPA shows nothing really when I ran it. I do daily backups and noticed that there was an "80" directory in C:\inetpub\wwwroot\wss\VirtualDirectories\ that was created today about the time the problem started. I removed that (after doing a full backup) and now get a 404 error when going to the owa website.

I found an article that referenced that the default website in IIS might not be started. It turns out that indeed was the case. I started it and its working...
