Exchange 2013 - Outlook cannot connect, and OWA / ECP inaccessible
Posted on 2013-06-23
Running Exchange 2013 with CU1 installed on Windows Server 2012. Still using default self-signed certificates at the moment. Everything was running fine until I installed the Remote Access Role on the server, and restarted. When the server came back up, Outlook clients will no longer connect to Exchange, and both the OWA and ECP web pages give "Page cannot be displayed".
I'm not clear whether the server restart was the trigger for the issue, or the installation of the Remote Access Role.
I uninstalled the Remote Access Role once again and restarted. However, the Exchange problem remains.
I tried temporarily disabling the Windows Firewall, in case installation of the Remote Access Role changed some firewall rules. But it didn't help.
All services which are set to start up Automatically are started.
In terms of diagnostic information in the Event Logs, there seems very little to go on. The only one that I think might have a bearing on the issue is an Event 5011 from "WAS" in the System Event Log. It reads "A process serving application pool 'MSExchangeRpcProxyAppPool' suffered a fatal communication error with the Windows Process Activation Service.".
Any suggestions, please?
