Correct. The site's accesible externally and internally nwo that I've
added it to my host file. My settings are listed as follows:
Back to Split-DNS
Internal IP: 192.168.1.8
External IP: 192.168.1.2
Router IP: 192.168.1.1
LAT: 192.168.1.0 - 192.168.1.255
Web Listener Config: 
   IP: 192.168.1.2
   TCP Port: 80
   SSL port: 443
   Enable SSL Listeners box checked
Web Listener Properties Sheet: 
   Server: ISA server
   IP Address: 192.168.1.2 - Maybe this is the problem????
   Use a server certificate to authenticate to web clients - box
unchecked
   Authentication: Basic with this domain - box unchecked
   Integrated box checked
