SYMPTOMS
If you try to use the Link Translation functionality on a Microsoft Internet Security and Acceleration (ISA) Server Web publishing rule that publishes Microsoft Outlook Web Access (OWA) servers, you are repeatedly prompted to type your logon credentials. This symptom occurs if you follow these steps:
 * 1) You use the Link Translation functionality so that you can specify https://owa. .com, and then be redirected to https://owa. .com/exchange.
 * 2) You try to access your mail box by using the https://owa. .com address.



CAUSE
This problem occurs because link translation does not correctly process the path part of the URL (Path Mapping).



WORKAROUND
To work around this problem, use the Redirect functionality of Microsoft Internet Information Services (IIS) to redirect the default Web site to point to the Exchange virtual directory.

For additional information about how to configure the Internet Information Services (IIS) server so that the root folder is redirected to /exchange, click the following article number to view the article in the Microsoft Knowledge Base:
