Hi Sandy!

I don't want to step on Steven's toes on this, but I looked at your
trace to see if I could learn anything. I noticed that your DNS
inquiries are being sent both to an external DNS (record # 2, Dest:
128.049.016.007, which seems to belong to the Naval Ocean Systems Center
in San Diego) AND to your router (record # 4, Dest:
192.168.000.001),from which they would probably be forwarded on to your
ISP's DNS. You seem to be getting replies back from both inquiries.

How do you have your TCP/IP on the Host Names tab? Do you have multiple
DNS IPs specified?

Steven, I don't understand all the traffic to the loopback address. Can
you explain, briefly?

Thanks!
