Re: Periodic http_500 errors

Hi,
From
http://www.pocketpcfaq.com/faqs/activesync/exchange_errors.php?sort=WM_5_Error%20asc

"Problem:
An internal HTTP server error occurred.
- OR -
Synchronization failed due to an error on the server. Try again.
- OR -
An authentication error occurred connecting to the server.

Cause:

Verify that the HTTP server is available and try again. May require user to
de-select sync items (Inbox, Contacts, Calendar, Tasks) and re-select them
to reset the sync key.
1. Windows Integrated Authentication is not enabled on the Exchange virtual
directory on the Exchange server. The Server ActiveSync component uses
Kerberos authentication when communicating with the Exchange server.
2. Windows Integrated Authentication is enabled on the Exchange virtual
directory on the Exchange server, but Kerberos is disabled via the IIS
metabase.
3. Kerberos is enabled, but IIS may return HTTP Status 401 every 30 Days
when using Kerberos on Windows 2000.
4. Sync is attempted while the mailbox is being moved.
5. User attempting sync is a member of more than 200 groups.
6. The Left Hand Side(LHS) and Right Hand Side(RHS) of the user's primary
SMTP address are both different from the SMTP address based on the default
recipient policy. (Fixed with Exchange 2003 Service Pack2)
7. The Exchange virtual directory on the Exchange Server is configured to
require Secure Sockets Layer (SSL). Server ActiveSync communicates with the
Exchange Server over port 80.
8. Windows SharePoint® has been installed on the Exchange server
9. The user composes e-mail on the device and attempts a sync when mailbox
limits have been reached on the Exchange server.
10. Anonymous authentication is enabled on the Microsoft-Server-ActiveSync
virtual directory on the server.

Possible Solutions:
1. To enable Integrated Windows Authentication on the Exchange virtual root
2. Re-enable Kerberos on the Exchange server by following the instructions
in the KB Article 215383. HOW TO: Configure IIS to Support Both Kerberos and
NTLM Authentication
3. If you are using Exchange 2003 on Windows 2000, obtain the hot fix
outlined in KB 329938 by calling Microsoft Product Support Services.
4. Attempt sync later.
5. Reduce the group membership or obtain the QFE fix outlined in KB 818526
by calling Microsoft Product Support Services.
6. Add a registry key. Use Regedt32 and locate
HKLM\System\CurrentControlSet\Services\MasSync\Parameters. Under the
Parameters key create a Reg_SZ value called SMTPProxy. Set the value to the
domain defined by the default recipient policy. For example, Microsoft.com.
Restart the IIS Admin service. If you are using a front-end/back-end
configuration this registry key needs to be added on the front-end server.
7. To configure the Exchange virtual directory to not require SSL
8. Configure Windows SharePoint to use Kerberos authentication by following
the steps in KB 832769 HOW TO: Configure Windows SharePoint Services to Use
Kerberos Authentication
9. Try to delete items in your mailbox to bring it within limits or contact
your Exchange administrator to change the limits on your mailbox.
10. Uncheck anonymous authentication on the Microsoft-Server-ActiveSync
virtual directory on the server. Basic authentication should be enabled.
11. See KB 817379: Exchange ActiveSync and Outlook Mobile Access errors
occur when SSL or forms-based authentication is required for Exchange Server
2003 if you are using SSL or forms-based authentication."

I am using exchange activesync with an Axim x50. Exchange syncing works
well some of the time. Other times, I get an http_500 error message.
When I do, sometimes just hitting sync over and over again will work.
Othertimes, I just wait until later and it works. When it does work, it
will just stop all of a sudden and give me the error. I'm at a loss.
Are there any places I can look to figure out what is going on here?
I've seen a lot of KB articles dealing with the http_500 error, but not
with intermittent ones.

BTW - I am using SSL for syncing.

Thanks

Adam
