So, which of boxes A and B have the 'resolvconf' package installed?  It seems 
like B does not but A does.  If A does not, then something else is modifying 
the /etc/resolv.conf file which I think should not.

The purpose of resolvconf is to manage the list of nameservers as interfaces 
(and their respective nameservers) come and go.
