Can't ping NIC

[Noozer]

I've got a Windows XP MCE 2005 system with SP2 installed. I'm having
problems getting an Intel 100+ Pro PCI network card working. I also have a
gigabit ethernet port built into the mainboard and it's working fine.


Gigabit connects to a router, which connects to the internet via a cable
modem. Firewall is not enabled on this port and I can get to services on
this NIC. This NIC is on my private LAN at 10.0.11.16.

The 100mb card is connected directly to another cable modem. NIC has no
problem pulling an IP from the modem. I can release/renew IP's without an
issue. This leads me to believe that the card is working... BUT, I am not
able to ping the IP of the network card. Originally, this card did have the
Windows firewall enabled, but I checkmarked the boxes that should allow
ICMP. I got no response to pings and cannot connect to services on this NIC.
I've disabled the firewall with no change. I've also deleted the NIC from
the Device Mangler and rebooted. NIC reinstalled fine and pulled an IP but
there is still no response from pings.

Both interfaces are set to automatic metrics.

Ideas?

....and in true PC fashion, the issue is resolved minutes after asking what
could be wrong.

This time I disabled the Windows firewall and rebooted. The NIC was
instantly pingable and passing traffic normally. Firewall is now enabled
again and all works well.

Very odd.

....and it stopped again.

All was fine until I tried to access my FileZilla FTP server through the
Gigabit NIC. As soon as I tried that the 100mb NIC stopped responding to
pings. 20 seconds earlier I was connected to the FTP server through the
100mb NIC without any trouble.

And no matter what I do I can't get it working again. Shut off firewall,
deleted NIC from device mangler and reboot. No joy.

I'm starting to suspect faulty hardware somewhere in this equation. Blech!

Watching the status window for this NIC, I can see the recieved packets
increment about once per second while I ping the NICs IP address. Sent
packets does not change at all.

Pinging the Gig port, recieved packets jumps by 3 and sent packets jumps by
5 per second.

Have you tried to see if there is an IRQ conflict?

What IRQ are the cards set to? IF it's the same, there's your potential
cure. Set one card to a different IRQ? Not keen on this IRQ sharing lark
myself.

Let us know how you get on.

Noozer - just a comment - you do not ping the NIC - the NIC has a MAC
address - the computer is assigned an IP address which you ping.

That's partly right, AJR, but there's more to it. Computers and NICs
don't have IP addresses. Network connections have IP addresses.

Windows XP creates a network connection for every installed NIC. A
computer can have more than one NIC, so a computer can have multiple
network connections and multiple IP addresses.

To see the IP addresses of all the network connections, open a command
prompt window and type "ipconfig /all".
