    Hello.

    On my W2K server I have two NIC's, one for the external connection to the internet, and one for the internal connection to my workstation. I was messing around (computers and beer, bad...) so I'm not sure what I've done, but here are the details.

    On the internal NIC I've specified an ip of 198.162.255.1, a subnet mask of 255.255.255.0 and a default gateway of 198.162.255.1 (I'm assuming the default gateway, because the server is cabled directly to the workstation, is the IP of the server.). Using a default gateway that matches the IP of the server was working, but now when I ipconfig the default gateway is blank. Furthermore, when I ipconfig on the workstation, it picks up an IP from DHCP, but again the gateway is blank. The workstation and server cannot communicate other than the workstation grabbing the IP address.

    Can anyone make any suggestions that might lead to a resolution? I'm fresh out of ideas.

    Thanks in advance.
    Kevin

    Change the third octet of your addresses to something other than 255.

    Why did that work? Obviously I have to expand my knowledge of IP addressing. What's wrong with 255 for the third octet?

    Cheers.

    No prob!

    255 is an illegal host and subnet address, it is a broadcast address. If I wanted to hit all the hosts on the 192.168.1.0 network (assuming a mask of 255.255.255.0), I would send to 192.168.1.255. Similarly, if I wanted to hit all the hosts and all the subnets in the 172.16.0.0 network, I would send to 172.16.255.255.

    Within the last two weeks, I have seen a really good post on here with the URLs of a couple of TCP/IP tutorials, but now I can't find it. :(

    Try this tutorial from Cisco for more information.
