Dear Friends, I want to take advantage of the routing capabilities of ISA server to let route two subnets with active directory relationship (parent-child) so, I need to permit all windows 2000 protocols for active directory replication, etc. I also need to let pass across ISA Server one of these domains to the internet. I configured one ISA server 2004 Standard Ed over Windows Server 2003, whit 3 NICs one for each domain and one for the internet. I configured all the networks, network rules and access rules. But, I could not reach the full routing between my domains. I think ISA server doesn't led mi access to its entire configuration and have something hidden, that I could not activate for the routing. Can you give me some tips? Thanks in advance Alexey
