Hi C, If you're getting a 404 and the OWA site is on the internal network, it indicates that there might be a problem with the Web Publishing Rule or maybe the Destination Set you were using the in Rule.

It seems that if I enable ALL protocols through the packet filter, all of a sudden I can access the ISA server. So part 1 of my question is why? Shouldnt the web filter take care of this? Second part is now Im getting the page not found error from IIS. Although the pages are there under IIS default web server and the WWW publishing service is running and if I right access OWA from the Intranet then I can access the pages. So now whats going on? Every single microsoft page on this OWA/IIS error relates only to exchange 5.5. Im using exchange 2000 on a domain controller. I at least have local logon privelages so it should work for me? Im using RPC which is fine, very slow, but just about usable. I would prefer OWA ------------------------------------------------------ List Archives: http://www.webelists.com/cgi/lyris.pl?enter=isalist ISA Server Newsletter: http://www.isaserver.org/pages/newsletter.asp ISA Server FAQ: http://www.isaserver.org/pages/larticle.asp?type=FAQ ------------------------------------------------------ Exchange Server Resource Site: http://www.msexchange.org/ Windows Security Resource Site: http://www.windowsecurity.com/ Windows 2000/NT Fax Solutions: http://www.ntfaxfaq.com ------------------------------------------------------ You are currently subscribed to this ISAserver.org Discussion List as: tshinder@xxxxxxxxxxxxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub')
