This makes some level of sense. I was experiencing the symptoms on both my
Win2k machines. I have a Linksys router but was manually setting the DNS
entires in both win2k computer since I use port forwarding. I also tried one
machine just using DHCP from the Linksys and I still had problems. It wasn't
until I set my Win2k machines with only one DNS entry (just pointed to the
Linksys router address) that my problems went away completely. Appently the
Linksys knows enough to forward DNS packets on to a DNS server. And
apparently it knows enough to always try the first DNS initially.
Interesting.
