Exchange server not serving mobile devices - how to troubleshoot?
- by chickeninabiscuit
Our exchange server has suddenly stopped serving mobile devices.  Attempts to connect result in our ActiveSync server returning HTTP 500.
It is serving outlook clients fine.
Our server is Windows 2003 SBS 6.5 SP2
There are no abnormal events in the system log.
I ran the "Exchange ActiveSync with AutoDiscover" at https://www.testexchangeconnectivity.com/ 
I've notice an abnormality in the exchange properties, Log File Directory shows:
  Access denied.
  
  Facility: Win32 ID no: 80070005
  Exchange System Manager
As shown in the following image:
I think it may be related to a recent issue we had here: http://serverfault.com/questions/40222/windows-server-2003-suddenly-unable-to-connect-to-anything
We followed a procedure to reinstall TCP/IP: http://support.microsoft.com/kb/325356
I've run the "exchange activesync" connectivity test at testexchangeconnectivity.com:
