Question : Authentication for OWA in Exchange 2007 fails.

Outlook Web Access in Exchange 2007 fails internally.

Everything was working but the Application Event Viewer kept generating an error message about disabling Anonymous access in Autodiscover.  So I disabled Anonymous access for the Default Web Site, Enabled Integrated Windows and Basic Authentication and applied it to the child nodes.  Since OWA requires SSL, I figured I was ok.  That's when all hell broke loose.  Now whenever I attempt to access OWA in-house at "https://10.0.8.3/exchange" I first get the IE7 "continue to web-page" and the login box, but when the login attempt is made I get the following error:

"Outlook Web Access could not find a mailbox for PE2950-XCHG\IUSR_PE2950-XCHG. If the problem continues, contact technical support for your organization and tell them the following: The mailbox may be stored on a Microsoft Exchange 2000 or Microsoft Exchange 2003 server, or the Active Directory user account was created recently and has not yet replicated to the Active Directory site where this Client Access server is hosted."

What are the default security settings for the Default web-site and child nodes in IIS?  I need OWA back up in a hurry.
