Root DNS Server Issues?

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??
