I have a Server 2003 SP2 server running Exchange 2003 SP2. The server is the only DC as well.
RPC over HTTPS used to be working around 4 weeks ago. Now it isn't. The remote users simply have Outlook showing as disconnected.
OWA works fine without any certificate errors.
I have run through a checklist to make sure all the registry keys etc are correct.
I can access the https://mydomainname/rpc
site and get the authentication box
I also cannot connect outlook using a VPN connection. I can ping the Server by name and IP address but the profile won't connect. I have tried creating a new profile and tried turning off Cached mode. Nothing seems to work.
