For the record, we have one primary and two secondary servers. The three portmasters default
to the primary and only use one of the secondary servers. DNS is heavily used on our system
but our servers appear to be doing an adequate job of load balancing. And no other programs,
or equipment seems to be experiencing the same problem.
Thought I would jump on the bandwagon...
Thanks...

P.s. We are quite happy with our Portmasters in general and have received pretty good tech
support when needed.
