When the notebook gets an internet connection, ntpd recognizes this. It somehow doesn't occur to it, though, that it might be able to resolve the servers, now. I believe this is the problem.

Right smell, wrong pooch :) Thanks for the pointer to the ntp buglist.
I've always had to restart named after losing / regaining an interface,
most noticeably after a suspend/resume (eg a low battery suspend), so I
run /etc/rc.d/named restart from rc.resume. This looks like a similar
issue perhaps, though I don't see why restarting only ntpd would fix it.
named is supposed to auto-probe for interfaces at a specific interval;
see the interface-interval option. I forget what the default is,
but on our servers we explicitly disable it by setting it to 0.
// We have no dynamic interfaces, so BIND shouldn't need to
// poll for interface state {UP|DOWN}.
// (will this fix need to reload after suspend/resume?)
interface-interval 0;
It's rare, maybe twice a year, that this laptop cum server suspends from
a 2hr+ lack of power - inverter failures, rewiring etc - so restarting
named on resume makes more sense than constant iface polling 'in case'.
cheers, Ian
