Hi kevin,
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.
