Netbios translations with Exchange and DMZ

Can anyone tell me how to allow an Exchange Server sitting in a DMZ behind a Firewall to be added to an NT Domain on the LAN attached to the same DMZ without having to add a second NIC card?  I'm having difficulty passing mail from the Exchange that sits in the DMZ to my LAN Clients who are on an NT Domain using Outlook.  I'm avoiding having to use 2 nics nor Map Netbios Names in the DMZ to prevent an easier attack to the LAN if the Firewall should ever be compromised.  The firewall is also running NAT.  Mail Packets are coming in and hitting the Exchange box, but Exchange in turn cannot send the packets to the clients on the LAN because it is not trusted with the LAN NT Domain because of Netbios Names and therefore have no authorization to pass packets to the LAN.

are you trying to connect your clients using POP3 mail or are you trying to use Exchange clients? what domain is your Exchange server currently under? As far as I remember, you really can't change the domain name on an Exchange server once you configure it. If I am wrong and you can, it's not an easy task.
