iPAQ 6340 - restore & Server ActiveSync error SYNC_22

I have an iPAQ 6340 and use Server ActiveSync to access our Exchange server.

This works fine when I configure the iPAQ from a hard reset.

However, if I backup the iPAQ (using the iPAQ Backup utility) and
subsequently hard reset & restore the backup I find that the Server
ActiveSync wont work.

I get the following errors:-

1. "Synchronization (sp!) Error" in a dialogue box when the scheduled sync
takes place
2. If I click on the "Errors" link on the ActiveSync page on the iPAQ I get
the following:
"A critical error has occured and sync failed. The next time you sync,
you will be prompted to overwrite the data on your device with data from the
server. You will lose only the changes made since your last successful sync.
Error code: SYNC_22"

However, the data is never over written, and the above errors appear at
every sync.

This error renders the backup/restore process useless, as the only way I
have been able to fix the problem is to hard reset the device and rebuild
from scratch.

All other functions work fine, and I have connectivity to the network.

Any help would be appreciated in resolving this issue.

Simon,
Is the Certificate you installed on the ipaq back in the device ?
Check under the certificates ....are you using a purchased one or a home made?

Is SSL enabled ? Is windows integrated authentication set for the virtual
directory of Microsoft-server-activesync on the server ?

By the way does the exchange environment contain Load balanced front end
servers ??? with 2k3 RTM and SP1 ??? if so.... maybe one of the front end is
not updated with Exchange 2003 SP1 ?

Have you also tried creating a new virtual directory and try to sync ???

Let me know

MSK
