As I understand it, it isn't so much DNS as windows. DNS is a request to a
known good address, and it is fairly quick. But if the DNS request fails
then windows sends a NETBIOS enquiry to the address in question asking the
name of the machine. If the machine is not running windows, or is no longer
accessible, this request will time-out, but it takes several seconds to do
so.
This is a pain in the neck. And other places.
Hmmm. maybe someone could write a DNS-only lookup function...

My experience has been that this is a DNS lookup issue. The response time
to/from your DNS server may be too slow. Try running it without name
lookups and see if that works. My solution was to upgrade to a PIII on
the box running Ethereal.
