All adapters bound to DHCP do not have DHCP addresses. The addresses
were autom
atically configured and can not be released.

Same setup and try to renew.

C:\>ipconfig/renew

(I wait about a minute and then)

The following error occurred when renewing adapter Local Area

Ping statistics for 127.0.0.1:
    Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
    Minimum = 0ms, Maximum = 0ms, Average = 0ms

Even after this the Local Area Connection Status shows no packets sent
or received.

I will swap out the nic and then test again. If packets are sent I
will have my answer.

BTW how do I check for packets recieved and sent on my Win 98
computer?

John, thank you very much with detail and the reasoning behind your
answers. It has helped very much.
