Check for firewalls? ZoneAlarm, Norton Security, McAfee, all block apps from accessing the net. Turn them off or reconfig them to allow Halo.
Open ports 2302 and 2303 for gaming.

Also, in your next post, list your computer specs, connection type and speed if possible, and any error messages that appear.
