Hi all, I have a back to back dmz (both ISA server 2000). with a web server in between. I'm would like to be able to authenticate users to certain pages on the web sevrver (IIS) based on their active directory account which only exists on the internal lan. What would be the best way to achieve this? At the moment, the web server and the exterior firewall know nothing of the active directory domain. Any advice/insights/input much appreciated.
