Is it possible; Windows 2000 pro client running isa firewall client on one Nic with connection sharing turned on. Second NIC running 192.168.0.1 Second computer connected to above computer via crossover cable with assigned IP address. When we try to connect to the Internet on second computer, ISA prompts for username, password, and domain. We enter login info from first computer.This works and browsing is working. MSN messenger does not work however. Is it possible to get it to work in this configuration? Regards Bob Cheeseman King Kommunications
