Adding additional computer problem

IP routing should not be enabled on the Win 2000 machine. If DHCP is not enabled, then you should either enable it or manually assign a usable IP address, subnet mask, and default gateway.

If you already understand IP addressing, you can just ignore the rest of my rather long post...otherwise, this procedure should be helpful in making sure your Win 2000 machine is set up correctly to use your router.

If DHCP is not used, the manually configured IP address, subnet mask, and default gateway of the Win 2000 machine must meet these requirements:

-IP ADDRESS ...in the same logical address block as the address on the router.
-DEFAULT GATEWAY ...the same as the router address.
-SUBNET MASK ...the same as the router subnet mask

To find the address and subnet mask of the router, simply use the ipconfig /all command on your working Win XP computer. The default gateway and subnet mask are the same as the router and you should use them on the Win 2000 machine.

I'll suggest a way to select a usable IP address...but this procedure assumes your subnet mask is 255.255.255.0. Let me know if your subnet mask is different from this and I'll modify this procedure as needed....

First, write down the default gateway address from your Win XP machine. Next, write down the IP address of your Win XP machine. The first three "octets" of these addresses should be the same....for example: 192.168.0. The last octet is in the range of 1-254, but you must avoid duplicate addresses, so the last number in the Win 2000 ip address will need to be something other than the the numbers you wrote down.

EXAMPLE: If the router(gateway) address is 192.168.1.1 and the Win XP address is 192.168.1.100, then you could safely use 192.168.1.221 for the address on the Win 2000 machine. The most important thing here is that the first three octets (numbers) in these addresses must be identical.

Let me know if you need assistance with applying these settings to the network connection in your Win 2000 machine. Good luck...and hope this is helpful.

Yes, the xp machine connects to the net. DHCP is not enabled. The ipconfig/all command brings up the correct static ip address, subnet mask, and default gateway. But it does also say under the ip configuration that ip routing is not enabled. I did have the 2000 machine connected when I first set up the router yesterday, but I booted up my laptop to try to set up a wireless connection, and then I had to reinstall the entire router set-up.
