We're getting responses from the root servers, the names just
aren't resolving. From a windows NT machine the error is "Non-
existent Domain".
Ah, I just noticed something. The packet length for the DNS
response is supposed to be 510 bytes but it's being truncated
to 128. What the heck would cause that??
