Windows Server 2003 / Domain and Remote Desktop to PCs on LAN

I've inherited a Windows Server 2003 LAN (Domain environment) with several PCs to help support.  Am currently trying to understand how Remote Desktop works in the environment.

We've got a Comcast gateway with several dedicated ip addresses.  Examining the Gateway settings, there's nothing set for port forwarding or DMZ, so I suspect that Windows Server 2003 is forwarding incoming Remote Desktop connections to PC's on the LAN?

One of the dedicated ip addresses is assigned to the WAN port of the Gateway.  I am able to use rdp to remotely access (Remote Desktop connection over the internet) to the server using one of the other (i.e. "2nd") dedicated ip addresses.  Appending a port # to the address connects me instead to a PC on the LAN.

ipconig /all on server shows 2 vmware adapters and a physical NIC

Where else can I look / diagnostics I can run to understand how Remote Desktop is configured for the LAN?

Can't figure out what interface the "2nd" ip address is bound to or where the port forwarding is configured for incoming Remote Desktop connections.

Appreciate help pointing me in the right direction.  Thanks-

Thanks, but as I said, router setup shows no port forwarding is being done by the router.
Unless your 2003 server acting as a router, it's not on the server.  Turn the server off and then try to access via RDP using the IP.  If you connect, it's DEFINITELY not the server.

Replace the Gateway with a standard router can you still get in?  

I'm not familiar with comcast gateways, but some systems have different sections that don't always make immediate sense for port forwarding.

if you could maybe bless us with some kind of model # for the router / gateway or even some screen shots of the user interface, it would be much easier to assist you here...

also on the server, go into the dhcp snap-on console and see if any IP addresses have been reserved matching up with PC you can remote into
Thanks for the help folks.

SMC 8014 Gateway

No reservations in DHCP (attached)
No port forwarding in gateway/router (attached)

Thanks for your help.  I was onsite a few days ago: there is indeed a (second) router connected to the Comcast gateway: that's where the port forwarding is being done.

Thanks again--
