Ok.

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]
