Exchange 2003 event ID 3031 server activesync - smart phones cannot get mails

Customer is unable to get his mails with his smartphone. it used to work. there was no configuration change. this problem appeared after the C: drive had no more free space.

The disk space problem has been solved.

Event ID 3031 is logged each time somebody tries to access mails with smartphones.

Here is a copy of windows application event log (in french ... please let me know if you need english translation). I dont know where to check in Exchange and IIS if some parameters are misconfigured (we did not modify any configuration at the time the problem occured).

Waiting for your advices - Thanks

Application Log Entry event ID 3031:

I think the problem you are having has to do with kebero authentication. Did you make any changes to your Active directory while resolving the drive space issue?

Download Exchange Remote Connectivity Analyzer tool from the link below. The tool simulates several client logon and mail flow scenarios.

Is the server part of Small Business Server?

If it isn't, do you have Forms Based Authentication Enabled (pretty login screen instead of just a plain windows username / password box)?

If you don't have Forms Based Authentication enabled, then please follow KB817379 and make sure you don't have the exchange-oma virtual directory and that the registry entry isn't listed in your registry.

If you can't get it working, please consult my article for the correct settings in IIS:

I am pleased to say it is solved by correcting configuration of Microsoft-Server-Activesync virtual directory.
The 'secure communications require SSL' was NOT ticked whereas it should have been.
Smart Phones are receiving their mails now.
Thank you for your precious help ...
