RPC over HTTPS disconnected

Hello guys

I have an issue with my outlook 2010 clients getting disconnected when they are on Outlook Anywhere. The Exchange server is an SBS2008 server. I have done a exchange Connectivity Test and here is the result. Can anyone shed some light as to what can be wrong? I have also disabled firewall settings on the SBS server and it has also no effect.

Hi Shreedar unfortunately the settings changes made it worse as suddenly my OWA and Active Sync was not working. I ended up calling MS in as it was getting serious fast and I got to know that there were more things wrong with it like the RPC and RPC cert directory in IIS were in the wrong website and application group.

Whoever build this server made sure made a mess of it to begin with.

Not the answer that solved the question but did point me to the right direction to start looking. Unfortunately it caused more issues after I made the recommended changes unknowingly there were more serious issues underneath the server setup as a whole.

Called MS to resolve.
