Those IP addresses for the computer that does connect are not in one of the local IP ranges, they're real external IPs, and are registered to the University of Buffalo.
Are you at SUNY Buffalo, or is your IT dept somehow using an external range of IP addresses that don't belong to them as their local IP range for their router?
Many universities require that a computer's MAC address be "registered" with them before they will assign it an IP via DHCP. This might be your problem.
Has computer #2 ever been successfully connected via Ethernet from any place on this network?
