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: 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:

The fix after two days of troubleshooting this issue is the following article: "The domain name may not appear in its correct form in the DNS record of a Windows 2000-based or Windows Server 2003-based domain controller" http://support.microsoft.com/kb/888048

On our SBS 2003 server I then had to: - uninstall the network card from device manager, do a scan for new devices and reinstall it -run "netsh int ip reset" -Reboot the server. -Run the Change Server IP wizard from Server Manager. -Run the connect to internet wizard -Run the remote access wizard.

After doing all of this the server and all features RRAS, Exchange System Manager, Exchange Activesync, RPC over HTTP, etc all work perfectly for me.
