Ethernet appears to be connected but actually isn't

[iluvatar]

Hi,

- Fresh install of Windows XP SP2
- Installed latest nVidia nForce 2 drivers (v5.10) which are required
for ethernet (motherboard is Epox 8RDA+)
- A single network connection appears
- When activated, it takes 1 - 2 minutes, but it eventually gets the
correct IP and gateway and DNS information from my router
- Windows does not present any errors anywhere at all

So, I try to connect to the internet. Won't do it:

- ping localhost works, but
- ping 192.168.1.254 (my routers's IP) doesn't work (timeout)
- ping <any intranet or internet host> doesn't work;
- resetting WinSock (netsh winsock reset) didn't solve the problem;
- resetting the IP thingy (netsh int ip reset);
- obviously I tried rebooting, reinstalling drivers, reinstalling XP again, etc
- and other computers (running various OSs including XP) work just fine
on the same router with dynamic IPs

The weird thing is:

- in any of the Linux distributions I tried, the networking works
perfectly on the same computer!

Does anyone have any idea how I can make my ethernet work in XP?

Never had this problem before in my life. I'm on the verge of throwing
the machine through the window...

Thanks in advance!

Something is blocking ICMP packets. Usually, that something is a firewall.

Connecting to the internet doesn't work either (like I said). I tried
both with and without Windows Firewall enabled. My router only has an
ingoing firewall, and all other connected computers do just fine anyway.

Your nVidia nForce 2 has its own firewall ...

I'm quite sure my motherboard doesn't have a firewall, it's not the
nForce 2 Ultra. The nVidia drivers don't install the firewall manager
anyway. I do have a nForce 3 and nForce 4 board, they do have a
firewall.

Please Google this forum for "nVidia". You'll find a few folks who have
learned, the hard way, that:
1) The drivers for nForce 2, 3, and 4 are the same.
2) Not installing the nVidia Access Manager leaves the firewall open (broken)
not closed (bypassed).

Listen:

the chipset on my motherboard does not have the built in firewall.
First of all, it doesn't ask to install the Network Access Manager.
Second, when I run the <driver path>/Ethernet/NAM/setup.exe manually,
it bails out with "Nvidia Hardware/Driver not found." Third, if this
firewall would be the problem, why would networking work perfectly in
Linux? Fourth, my motherboard's manual doesn't mention a firewall
anywhere, simply because (I believe) it's only present in nForce 2
*Ultra* chipsets.

So, again: the chipset on my motherboard does not have the built-in
firewall. I appreciate your help, but it's not the nforce firewall.

OK, have it your way. Let's start from the beginning. Look at "browstat
status", "ipconfig /all", "net config server", and "net config workstation",
from each computer, and diagnose the problem from the bottom up. Read this
article, and linked articles, and follow instructions precisely (download
browstat!):

Sorry, I was just a little annoyed because I had to say twice that
there's no nforce firewall.

However, *this* answer is helpful and I'll look into the articles you linked.

Thanks!
