Exchange 2010 / Autodiscover certificate name invalid

Last Modified: 2012-05-09
I have an Exchange 2010 server, and both local and remote Outlook clients running both 2007 and 2010.  

All of my LAN users, regardless of Outlook version, have no issues.

All of my remote users, using a VPN, soon after logging into Outlook(Exchange), get a dialog box indicating that the name on the cert is invalid or doesn't match the site name.  I've seen a dozen different "solutions" which apply to Exchange 2007, as well as notes that many of them don't apply to 2010, such as the whole "2 certificate" issue.  I'm bewildered, since this only affects folks on my VPN.

DNS entries for my mail server (BG-Exch2010.burgessgroup.com) and for autodiscover.burgessgroup.com are both identical.

Running a packet capture on the remote machine is useless since the data is on the VPN (and thus encrypted.)
