I'm trying to host multiple websites on my ISA server which is also my web and mailserver. My default website and my exchange OWA works perfectly. I have several other internet domain names registered with Internic which point to the external network interface of my ISA server. However when I try and go to any of those domain names I just end up at my default website. All my settings in IIS are set to use hostnames and worked perfectly before IIS. I've followed the instructions from http://support.microsoft.com/default.aspx?scid=KB;EN-US;Q305052&; although this isn't specifically for having iis onthe same server as ISA and doesn't work. Can someone please help me with this. Many thanks.
