Actually, the DNS servers are provided by Verizon FIOS and are working fine
for the browsers on Win 7. I'm getting a "Looking up <host-name>" message
for each host referenced by the page. I'm not a network expert, but I am an
expert network programmer. I expect the local IP stack to cache IP
addresses after DNS searches. That doesn't seem to be happening.
