SYMPTOMS
You install Microsoft Exchange Server 2003 on a computer that is running Microsoft Windows Server 2003. When you log on to Microsoft Outlook Web Access to obtain access to a mailbox on the server that is running Exchange Server 2003, a blank HTML page is displayed. Additionally, if you enabled the Show friendly HTTP error messages option in Microsoft Internet Explorer, you receive the following error message:

Error 500 – Internal server error is observed on the client.



CAUSE
