Help: Network connection problem

Just did a format and install of XP on my new Neo4. If I go in to network connections I see two network connections. "Nvidia Networking Controller" and "Marvel Yukon 88E805 PCI-E Gigabit Ethernet Controller." If I plug the cable into the nvidia connection I cannot connect. If I try the Marvel connection everything works just fine. I've checked as many setting as I can and they all seem to be the same, except the nvidia controller can't refresh it's ip address and won't let me connect. Any ideas?

Have you installed the latest v6.39 of the nVidia Chipset Drivers? You can find them here (I believe you need the Standalone Kit for the nForce4)...

Windows XP - nForce4 Standalone Kit (6.39)

...or from MSI here:

Downloading them as we speak. I'll let you know if it works out
thanks!

If you are on cable, shut down reboot your modem and then reboot your computer. I had the same problem on my nf7-s. It sounds silly, but it worked for me.
