    OK. Thats your private network.

    Ok this is right, and 10.2.1.254 is reachable in theory.

    Are you running NIS/YP ?

    How long does it take to fail. If it takes a minute or two then its failing
    to talk. If its instantaneous then something system side didnt like it.

    BTW: A config matching your network and RedHat 3.0.3 with the addresses
    quoted works on my home test net. That of course doesnt help you.

    Do both the listed name servers work ? [eg dig @secondserver www.my.net]
