Looks like ISA not configured properly. From internal, user by pass ISA. Please provide more information to the list 1. URL used from external (home ) 2. URL used internally 3. How was the ISA configured (e.g. bridging SSL) /Gill _____ From: Alex Gonzalez [mailto:AGonzalez@xxxxxxxxxxxxxxxxxxx] Sent: Saturday, August 20, 2005 3:48 AM To: [ExchangeList] Subject: [exchangelist] Issue with OWA 2003 and ISA http://www.MSExchange.org/ We just deployed ISA 2004 to publish OWA 2003. We are seeing something strange with authentication. For users that are trying the new OWA for the first time at home they are getting a 404 error when they try to log in. But if they have logged into the new OWA site from internally first they are not receiving the error. We recently replaced our 5.5 front end server with a new 2003 server. All the back end is 2003 no service packs. Has anyone seen this before?
