thanks for the reply.
It turns out that my dns setup is fine, however i did discover that my
internal dns server ( G4 500 MacOSX 10.3.5 Bind 9.2.2 ) was the
culprit. not sure specifically what about this box made things slow,
but i switched to my original configuration with 10.1.2 and all is
working well. i suspect the 10.3.5 upgrade screwed things up. i have
been hearing rumors about BSD systems and IPv6 issues.
I'll have to dig deeper to find out what the problem was.
