remote access via OWA and Outlook not working for SBS 2011 server

We have a problem that needs debugging. Easy for someone with the right Exchange/Server/SSL expertise! We recently moved from one physical site to another, and now Outlook won't connect to Exchange 2010 Email remotely. Neither does remote./OWA work. IE and Chrome come back with SSL Connection Error #107 (Protocol Error). Works within the network itself, Outlook clients and OWA work fine. Need to be able to fix this so remote email work again. Some more details: - Worked before the move. Now new ISP and IP address - Running SBS 2011, which uses Exchange 2010 - Ran TestExchangeConnectivity - comes back with the following error: The Autodiscover service couldn't be contacted successfully by any method. Experienced help much appreciated! Sifet
