Actually, the dns logging in windows is pretty damn good.
Whip that up full bore and filter for the ip of your wkst, then query away.

  Anything in the logs of either DC or the clients?

  If you try doing a DNS query with NSLOOKUP to the IP address of the

  Try a network sniffer, filtering on UDP ports 53, 66, and 67.
