Ok, here's a weird one for you guys. Ive tried different drivers and i still get intermittent loss of lan connection when using the onboard Nvidia LAN. Sometimes i cant even connect to other computers on my network because of it, even though they show in the workgroup. Ive done 3 fresh installs thinking it was my RAM at fault.

So last night im on one of the other machines and i notice the MSN Messager keeps logging on and off on the SLI rig. Each computer on my network has their own passport and are on each others buddy list. I popped the cable out the back of the SLI and installed it into the Marvell Gigabit Lan port instead. All problems fixed. Occassionally i would get BSOD using the onboard Nvidia LAN with FTP programs and such.

Now that i have isolated the problem, has anyone else experienced this problem on their DFI or NF4?
