Specs: Windows XP
Hi there I'm a newbie to this site
At the moment I am trying to set up the smallest of networks i.e 2 computers, Xp and Server 2003, but I am having problems and would be greatful of any help given...........thanks

Here are my devices
2 computers:
Client01 (Xp Professional) AMD Athlon(tm) 64X2 Dual Core Processor 4200+2.21 GHz. RAM: 2GB
Server01 (windows 2003 Enterprise) Pentium4 CPU 2.66GHz, RAM:1.49 GB

Cable ModemScientific Atlanta EPC2100(Webstar)
Switch (5 ports)

I have connected the the 2 computers to the Switch using straight thru' cables and connected the modem to the switch using a crossover cable

Server01 configuration:
The server is configured to use Dhcp, Dns and Active Directory the ip addy is (Dns and Dhcp are up and running)

Local Area Connection properties on on network card

ip address:
Subnet mask:
Default gateway:
Preferred Dns server:

I have another network card on the Server (1394 Connection)

Client01 configuration
As I have only one physical network card on this computer, which is my main computer this network adapter uses the Cable modem config

I have installed a loopback adapter, but to no effect......

How can I get this up and running, it worked a while back but I've forgotten what I did................Grateful in advance for any help

You need to manual configure both computers with an IP address in the same sub net, i.e These are private IP addressees that do not exist on the Internet.

As you have it now the client computer is getting a public IP address from the Modem and that is never going to work. You need to remove the modem to get the two computers linked,

If you wish to share the Internet between the two computer you need a router. You cannot do it with a switch. You could configure the Server 2003 computer to route the Internet to the other computer but you would need another Network Interface card to do that. A router would be the simplest and most reliable solution.

I you already have a second NIC on the server plug the Modem into that. You need to configure that to get its IP address from the Modem. Remove the default gateway and DNS server addresses from the existing NIC, they will come form the Modem.

Something I missed before, the IP address and default gateway can never under any circumstances be the same address. You just end up going round in circles.

That will give you Internet Access on the server. If you want the client computer to have Internet access as well you will need to bridge the two NIC in the server so that they can communicate with each other and whatever they are connect to.
