OptiPlex 780 drops packets

Hello Everyone,

I'm having a problem with a Dell OptiPlex 780, 64-bit, Windows 7, machine that is dropping packets. The NIC is an Intel 82567LM-3 GB. So far I've done the following:

Swapped out the cables on both ends - PC and Switch
Updated the NIC drivers
Disconnected the mapped drives and reconnected them

When I ping the file server from the PC I get a significant % of packet loss.

Also, just to be sure of the cable issue -  I connected another computer to the network port in the users office, and all worked well - from the other computer.

Any help will be appreciated.  Thanks.

Alicia

Happen to have a USB/PCI Network card you could pop in to isolate the problem to either the PC or the NIC Card?

Or use something like UBCD/Knoppix, to boot from, and test externally of Windows. If it works in Knoppix, then you know it is a driver/config issue, and if it doesn't, replace the card.....

John,

No, I don't have another card handy and I'm not familiar with UBCD/Knoppix.

If you just DL the iso, and burn it using your favorite iso burner, like CDBurnerXP, you can boot to it and run it as a standalone OS, to rule out YOUR installation of Windows.....

It is just a linux live distro....

Thanks everyone for you help and ideas.  It turned out to be a bad NIC. Replacing the NIC solved the problem.
