Trying to setup NAT on a standalone 2k server within a 2k network. Connection PPP demand dial. DHCP and DNS setup on Domain Controler with Active Directory.

Have RRAS set up as router with NAT on Standalone Server with modem and NIC. Modem setup as public interface, NIC as
private (local) interface. Fixed ip address (192.168.1.15)
assigned to NIC on NAT machine, and reserved in DHCP Server's Scope. IP address of DC running DHCP and DNS fixed
(192.168.1.10) and also reserved in DHCP scope.

DNS and DHCP functions in NAT disabled. DHCP Relay Agent added to RRAS Protocals, pointing to local DHCP Server, and Relay of DHCP packets enabled.

DHCP on DC set up to assign address to all workstations as well as point to DNS (local on DC) Default Router (NAT machine) and WINS Server (local on DC). Functioning as expected.

DNS on DC set up as Not Root and forwarders set up to point to ISP's DNS servers (2). Resolution and updating on forward and reverse lookup zones as expected when local workstations release and renew DHCP leases.

Problem....NAT will dial out on demand when a non local IP address is entered either through ping, or as an IP address entered in MS I-Explorer. Tracert from a workstation shows routing through the default gateway (NAT Machine). Unable to resolve internet based host names. Local host names ping, Internet host names return unknown host. What am I doing wrong in the DNS setup????

Appreciate any input you all may have
TIA
