Fredrick or anyone else.... Makes more sense, but a few more questions also. Does ISA Server actually see the www.domain.com and determine where it will go based on the FQDN. My thinking is more IP based, but you said it uses headers. ISA server will look at the domain name as the header? We are wanting to keep it very simple and publish a straight www.domain.com to hit internal web server and mail.domain.com to hit Exchange OWA. So below is how we would configure correct? 1 - Name: Public Web Description: www.domain.com Destination Path: /site1/* 2 - Name: OWA Description: mail.domain.com Destination Path: /public/* /exchweb/* /exchange/* So the Destination set is based on where the user will be coming from. ISA will see the FQDN as that destination and redirect it to the correct internal server's Path. Just want to make sure I have this right. Thanks in advance for your time and look forward to your replys.... Joe
