Two practical paths exist: use a hardware router (as suggested) or make the 2003 server act as the gateway (as noted). Below are concise, actionable pointers and common gotchas for both domain and workgroup deployments so the setup works reliably and safely.

If the server will be the gateway, pick one NIC to face the Internet and give the other a static private IP for the LAN (for example 192.168.1.1/24). Do not put a default gateway on the LAN NIC — the gateway belongs only on the Internet-facing interface. Run a DHCP scope that hands out the LAN IP as the clients' default gateway and use the server as DNS for domain clients. Configure NAT on the server (RRAS or similar) so LAN addresses can reach the Internet. If your ISP uses PPPoE, ensure authentication runs on the device that terminates that connection.

Domain vs workgroup notes: in a domain, clients should point at the domain controller for DNS and receive the domain suffix via DHCP; DNS forwarders on the server should target trusted public resolvers so external names resolve. If the server is also a domain controller, be conservative — consolidating NAT/router duties onto a DC increases complexity and attack surface; a separate router is preferable when possible. In a workgroup, you can use simpler DHCP/DNS settings or public DNS on clients, but keep the same gateway/dhcp rules.

Quick troubleshooting checklist: from a client run ipconfig /all to confirm IP/gateway/DNS, ping the LAN gateway, ping 8.8.8.8 to test raw Internet reachability, and nslookup to verify DNS. Common failures are: gateway set on the wrong NIC, firewall blocking NAT/forwarding, or DNS misconfigured. When feasible, prefer a dedicated hardware router for better security, performance, and simpler AD environments.

Do you have a router just use the router to share internet

If you don't have a router, and want to use the server as a router here is the method:

Lan card one: Internet plugged in.
Lan card two: has to go your 2nd computer or switch.

Proceed to setup RRAS as a NAT. Here is a step by step guide on how to setup NAT on Server 2003.

Good Luck
