Exchange 2010 OWA Not working

We are having problems with an Exchange 2010 SP3 server running on Small Business Server 2011 (Server 2008 R2 essentially).  All of a sudden users are not able to login using OWA.  Users get the message below.  We have tried reinstalling SP3, and update roll-up 10.  I have also run sfc /scannow and .Net Framework Setup Verification Tool which found no errors.  There are a few random Exchange errors that seem unrelated but I will post those as well.

Microsoft Exchange could not find a certificate that contains the domain name in the personal store on the local computer. Therefore, it is unable to support the STARTTLS SMTP verb for the connector Windows SBS Internet Send NUMBERS with a FQDN parameter of If the connector's FQDN is not specified, the computer's FQDN is used. Verify the connector configuration and the installed certificates to make sure that there is a certificate with a domain name for that FQDN. If this certificate exists, run Enable-ExchangeCertificate -Services SMTP to make sure that the Microsoft Exchange Transport service has access to the certificate key.

This almost seems like a DNS or IP issue. Did the server's IP change? Has IPV6 been accidentally disabled? Is DNS set to use itself then use the proper root servers to access the internet?
Please check the if all the Exchange services are in started mode or not?

The server IP address has not changed and DNS resolution is working fine.  All Exchange and other automatic processes are started and running fine as well.

I did correct the last 3 errors, 2 by removing an invalid routing group connector through ADSIEdit.msc and the last one by specifying a FQDN for the send connector that matched a FQDN that there was a certificate for.  Neither of those seemed to help either though.

I ended up removing the Exchange Client Access Server Role by downloading and extract Exchange 2010 SP3 and running: /m:uninstall /r:c

When I went to re-install the role it would not run so I had to do that by using the add/remove programs control panel and then pointed the installer at the sp3 installation files.  After doing that I re-ran the Update Rollup 10 setup and all is well!
