We recently tried to setup RPC over HTTP for a remote user to connect to our 2003 SBS Exchange Server from Outlook on his workstation. OWA is not powerful enough to handle everything he needs. RPC over HTTP is something we want to get setup, but right now this isn't our main problem. We made some changes on certificates to point to mail.domainname.com from just domainname.com. Once we made this change we lost access to every part of Remote Web Workplace and OWA. We reverted back and can now get to Remote Web Workplace (RWW) fine but Exchange OWA does not work. We get a 404 "Page Cannot be Displayed Error." Please Help! I tried restoring the metabase to earlier but can only go back to the original from 2 years which totally screwed everything up or an hour or less ago. Right now, everything is accessible with the exception of OWA. I don't think the problem lies with Certificates, because I still get the prompt to accept it and I've looked at security and permissions over and over, but I could have missed something. By the way, OWA does not work on the inside or the outside.
