Windows 2003 network setup for Internet sharing with the windows XP client

I am having 2 computers, out of which the first one is having windows 2003 server and second one is having windows xp OS. In the first computer I am having the cable broadband service and the service provider has given me the static ip address. I want share the broadband connection with the second computer and for that I have installed a LAN card in the first computer. I have also installed a switch, because the distance between the computers is more than 25 mt.

Please give me the step by step solution how do I setup the network and share the broadband connection. I am planning to use the winproxy software for the connection sharing.

Thank you.

Get a broadband router appliance to do the job...like this

Much easier solution and economical.

If you want to expose parts of your W2K3 server to the world, you will have to use port forwarding.. more information here

all you need to do is have your cable modem attach this way...

Ideally, the switch is a broadband router with a built in switch.  Using this, the static IP would be on the outside WAN connection and it would provide DHCP and NAT for your two devices on the inside.  

Barring that, set up the 2003 server with Internet Connection Sharing

I think I need to focus on my point more clearly. I have the D-Link DES-1008D switch, which is helping me to connect the two computers physically.

The Server computer Windows 2003 Server is having two Lan Card(One is built in with the 915GAV motherboard and second one is the D-Link Lan card).I have attached the  D-Link DES-1008D switch to the d-link lan card.The default card is used to for the incomming cable broadband connection.

Now I have configured the TCP/IP of the D-Link card and given the static ip as 192.168.100.10 for the Server(windows 2003) and 192.168.100.20 for client(windows XP).I am able to ping the xp machine from server,but the reverse is not happening.How o solve this problem.

Please don't put comments.I need the real solutions.(I am not hardcore network professional)

Usually, this is either 1.) Firewall or 2.) Subnet mask incorrect.
1.) Ensure there are no software firewalls running - ICF, ZoneAlarm, etc.
2.) Check the subnet mask - make sure it is exactly the same on both PC and Server.

@prolay01...the way you are setting up your network is inefficient. Windows Internet connect sharing puts a burden on the server.  If you use the router appliance that I mentioned above you don't need that 2nd network card in your system, and you just have to statically assign an IP to the server.  In addition, the systems can connect independantly to the Internet without the workstation or even future workstations depending on the server to be running.  Lastly, If you want to run Internet Information Server, FTP, or other true server applications, you won't be inhibited by Internet Connect Sharing's firewall configuration.

However, I will offer this should you pursue ICS

Server configuration
NIC1 (WAN)
IP addresss >>>>obtain automatically from DHCP server
DNS server >>>>obtain automatically from DHCP server

NIC2 (LAN)
IP address 192.168.1.10
subnet 255.255.255.0
Gateway 192.168.1.1

Workstation Configuration
NIC1 (LAN)
IP address 192.168.1.20
subnet 255.255.255.0
Gateway 192.168.1.1

---more server configuration----
DHCP server NOT enabled
Active Directory installed
Internet Connect Sharing Enabled w/ Firewall


you connection will appear as follows

cable modem-----------Server NIC1----------Server NIC2------------DLINK switch----------Workstation NIC1

In my case I have installed the Active directory.But unfortunately,I am not able to add the workstaion to the Active directory.As you mentioned i have added the default gateway in both server and workstaion. but in workstaion when i am trying to change the domain name, its saying that the domain chaudhury.home is not correct. from the server i have tried to add computer by searching the computer object, here it is not showing the object.

what else shuold i check.

with warm regards,

Now I am little bit confused.

Let me describe steps i have performed while setup the peer-to-peer network betwwen the server and workstaions.

The server pc config(windows 2003 server):-

NIC1 (Inbuilt lan card)
IP addresss :- static ip provided by the broadband prrovider.
Gateway :- ip provided by the broadband provider.

NIC2 (LAN)
IP address 192.168.1.10
subnet 255.255.255.0
Gateway 192.168.1.1

Workstation Configuration (windows xp)
NIC1 (LAN)
IP address 192.168.1.20
subnet 255.255.255.0
Gateway 192.168.1.1

The server does not have the DHCP role enabled in it. the Active directory service is installed.I need further assistent to configure it.

In the windows XP machine, I have tried this:-
I have right clicked the My Computer-> properties->change and tried to join the domain which i have created as chaudhury.home from default workgroup.it is showing me the error that the domain name is not correct with the _tcp... kind of error.

Please tell me the detailed steps to correct the problems.

with Warm Regards,
prolay
