This was my mistake.  My desktop was sending out a request that 
didn't get a valid response, so it then sent a second request 
with out internal domain appended to the original request and 
*that* is what generated an actual error.

So, we're not getting a specific error response, it's just that 
the responses are being truncated to 128 bytes even though the 
IP header says that they all should be longer.

I think this is occurring because I'm being a dork and trying 
to do an nslookup on a root server and they're not designed for 
that.  An nslookup directed at another ISP's name server seems 
to work just fine so the problem must lie in our own DNS server.

Nothing was changed recently and that is the perplexing 
issues.  It just appeared that it couldn't reach any of the 
root servers, so we--being unwashed and unschooled--went 
barking up the wrong tree.

My apologies, and I'll get back to hounding our DNS admin.  :-0
