The question I would be asking is "Where is countermain ?". If all your
sites are looking it up, but it's only used locally to each, then
perhaps the new network is trying to provide a global address for it? I
still prefer fixed entries in the hosts file so I know what is going on.

I've had problems at a number of sites where the 'experts' have put in
new hardware to 'improve the network'. In most cases they broke things -
and not just Firebird - so now I have no problem telling them that the
cost of fixing things will be billed! Amazing how quickly things get
fixed ;) One site still has the old network running some applications
that they can't work out what to change on the new (very expensive) one
to make them work again :)
