In your first message, you said "All server virtually the same 
configuration."  What are the differences? What do the servers that do 
resolve have in common that is missing on the others?  What do the ones 
that fail have in common?  Could it be an issue with IPv6?  Are they all 
running the same version of bind?  Differences in named.conf?  Could there 
be differing firewall rules for the different servers?

Try running dig from each server.
