No, not really -- the key was that he didn't see to be
getting ANY updates for Macs (ever) and had no
problems (yet) with other machines.

Eventually he has to deal with the credentials if
the two DHCP servers lease to (any of) the same
names (clients more from subnet to subnet or both
DHCP servers offer on same subnets.)

That is your point and he he needs to know about
that so you did well too inform him, but it isn't going
to fix his initial problem and therefore needs to be
differentiated from the direct issue in the question.
