Autodiscover in Exchagne 2007 Not Working from Outside Non-domain computers

I have a relatively new Exchange 2007 environment on a single server.  Everything (OWA, internal email, send. receive...) is working fine except I cannot get Outlook Anywhere to work from the outside on domain or non-domain computers running Outlook 2007.  I've scoured the internet and EE looking for resolution and not finding it.  I receive a variety of errors relating to certificate name not matching and continuously having to log on to Outlook with no success.  I have a UCC/SAN certificate from Entrust.  

Please see below for the results of some popular tests and requests for information.
