I am installing a new Cisco PIX 515 Firewall with 6
ethernet ports. I will have Windows 2000 Active directory
servers in 1 domain in multiple segments on the PIX. They
will have to talk to each other so I will have to create
an access-list to open ports. What ports does active-
directory use?

Thanks

Tom
