Server ActiveSync Event Errors. Active Sync not working

Greetings,

Exchange 2003 stopped allowing our iphones to sync via active sync. I am getting Event ID 3005  in the event vwr. When attempting to access the mailbox from the iphone , it is triggering the alert. Iphone reads "cannot get mail. The connection to the server failed.
Event Type:      Error
Event Source:      Server ActiveSync
Event Category:      None
Event ID:      3005
Date:            11/19/2010
Time:            2:31:07 PM
User:            Domain\User
Computer:      computer
Description:
Unexpected Exchange mailbox Server error: Server: [server.domain.com] User: [user@domain.com] HTTP status code: [501]. Verify that the Exchange mailbox Server is working correctly.

For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.

The only successful post I have seen about this error is removing the headers from the default website in IIS. That did not resolve.
Any help on this would be great.

thank you !!

Went over level one technician notes and saw that he added a registry key during initial troubleshooting.  This key should have only been added when creating a second virtual directory in IIS.  I pulled another 2003 exchange server and noted that the below key did not exist:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MasSync\Parameters\ExchangeVDir

The only time you should create this key is when you are creating a secondary virtual directory.

I removed this key, restarted the IIS admin service, and active sync is now working.

What is the reason for not using SSL  You can buy an SSL cert for $50 and that would secure your communications considerably.

Alan: SSL has been proposed; but working without it .

viralrathod: I have walked through the guide, other than the SSL options my config is spot on.

do you have FE-BE topology or just back end server ?

Alan HardistyCo-OwnerCommented:
The only reason for creating the 2nd virtual Directory on an Exchange Server is if Forms Based Authentication is enabled and this forces SSL onto the Exchange Virtual directory, requiring exchange-oma virtual directory to be created which has SSL disabled.

This is all covered in KB817379 from Microsoft.
