The explanation there says, "All of these messages indicate a flaw in 
the implementation (not the configuration) of the remote name server."

The Army hides the version of their DNS server, so I have no idea what
they are running.  My question now is this - If the Army is running
BIND (8.x or 9.x), is there any way for them to have the errors I am
seeing?
