	(216.231.105.163).

	That would make sense, but the first authoritative server is 
216.231.111.14, in the same /19 and the second is 209.51.161.86 which is
offsite. We have checked all packet filers and allow-query and it should
not be a problem. PLUS, the 2nd major time it happened, it stopped almost
exactly 4 hours after it started with NO changes anywhere in our 
configurations or network.

	When you did an nslookup, it said there was a timeout and then fell
over to the second server in the resolv.conf, which, coincidentally, its
216.231.111.14 .
