Two ethernet cards, now only one....


B

bryan forst

Im working with a Win2000 Pro peer-to-peer network of 4
machines. We were sharing a dial up connection via a proxy
server, everything was working fine.

Then I got DSL installed. I removed the modem and replaced
it with a second ethernet card. No connection to the
internet. Moved the DSL connection to a machine that had a
single ethernet card and all worked fine. Added a new
ethernet card to that machine, adjusted the proxy settings
and all machines can now see the internet and work fine.

All except the machine i originally put the 2nd ethernet
card on.
I changed IE to point to the new proxy server, just like
all the other machines, but it doesnt know it has an
internet connection. Pinging doesnt work, nothing.

Doing on ipconfig it seems to me that the machine still
thinks it has the 2nd ethernet card installed. Ive removed
it via the "Add/Remove hardware" option on the control
panel but to no avail. Here is the ipconfig output:

The other NIC may still have some registry entries left behind, thy the

Thanks for the info. I was hopeful since i did get this
error message when adjusting the IP setting of the card
that is still in the machine. However the solution
outlined did not solve the problem so it must be something
else.

cleared out the arp cache and still getting the problem...
checking more resources to see what else i can do beside
pull the network card out, search the registery for
entries of the ghost nic and start over!
