Consider the following scenario. You follow the steps in "Method 2" in the following Microsoft Knowledge Base article to create a secondary virtual directory:
817379 Exchange ActiveSync and Outlook Mobile Access errors occur when SSL or forms-based authentication is required for Exchange Server 2003
Then, you enable forms-based authentication. In this scenario, Direct Push does not work in Exchange ActiveSync in Microsoft Exchange Server 2003 Service Pack 2 (SP2).
This problem occurs because the client does not use the secondary virtual directory when the client uses the WebDAV Subscribe command.
