Please help me with my lab.

Basically, my Windows 2000 server has two network cards:

NIC1 Realtek 8139 10/100 Fast Ethernet
NIC2 SiS900 10/100 Fast Ethernet


NIC1 connects to Hub1 then to three stations (one NT4 and two 98SE)
NIC2 connects to Hub2 then to two stations (one ME and one 2K Professional)


Now, NT4 can see 98SE well and vise versa. ME can see 2K Prof and vise versa.

But NT4 or 98SE just cannot see ME or 2K Prof.

I understand I have to include Routing Talbe something like that.

Please help 'how' can I configure it?

Thanks

Presumably you're using tcp/ip on both nic's.
You need to make the gateway address of one nic the ip address of the other.
eg.
1ST NIC
ip 192.168.90.1
subnet 255.255.255.0
gateway 192.168.91.1

2ND NIC
ip 192.168.91.1
subnet 255.255.255.0

You will also need to enable ip forwarding on the server. All client m/c's should have their gateway address as the relevant server NIC for their subnet.
Check to see if all clients can ping each other (local and remote).
Then if you want to use netbios names to see m/c's in network places, set server to be WINS server for network.
Also some windows m/c's have difficulty with netbios names on other windows versions so you may need to set up local lmhost files on individual clients.
Good luck, it might sound a bit complicated, but go step by step it's not too bad.

You should add a routing protocol to the interfaces and enable "Enable IP Routing" check box.

You need to setup your Windows 2000 server as a router.

1) You need to install the Routing and Remote access component.
2) You then need to configure RRAS as a network router.
3) Open the RRAS console, right click on your server and click properties. On the General Tab select the Router checkbox and then select LAN routing only. (I'm assuming you are not using demand dial in your setup, there is no need)
4) As paullid stated, the clients need to have their respective gateway configured correctly. (i.e where do I sent this packet if it is destined for a remote subnet).
5) The static route table should be built automatically at this point. Check it out by opening the RRAS console again, right click on the server, then click on Show IP routing table. (Hopefully, you know how to analyze a route table ).

If things look ok, go ahead and try pinging clients that are local and on the other side of the router via ip address. If successful in your ping tests, you are good to go. If not, you may need to add the static route for your test environment.

HTH!
