First - dual homing Exchange 2003 isn't recommended. Ideally there should be a single NIC in the server and then you have a router in front of Exchange with port forwarding enabled. Dual homing can cause problems. You need to change your MX records to point to the static IP address from your ISP. http://exchange.sembee.info/network/dnsconfig.asp No records are required on the local server.
