If I really want to know what is different between two boxes, I'll do something like NFS mount one into the other or rsync their /etc trees somewhere on a common host and let diff -r walk through them.
As indicated above, I already know the difference between the two boxes.
I find that a little hard to believe, since they behave differently and you seem not to understand why.
Are you sure this isn't as simple as having (and using, check your resolv.conf) a caching name server running on one box so most lookups are resolved locally while the other is making the query to something slow?
resolve.config is the same on the two boxes.
Assuming you mean resolv.conf, is the the first choice one of the boxes in question?
