RE: [Fwd:] Nvidia NICs with duplicate mac addresses
This reminds me of a story I was told a while back that there was a batch of 3com NIC's that all went out with the same MAC from the factory. I never found out if that was a rumor/urban legend or the truth. Anyone know firsthand or have an article about that? -Scott -----Original Message----- From: Robert E.

Copying from a different email list... mac address 04:4b:80:80:80:03, was showing up in multiple places across the network. I googled the mac address and discovered that other people are having the same issue with this mac address. Below are some links describing the problem: http://forums.nvidia.com/index.php?showtopic=22148 http://www.nvnews.net/vbulletin/archive/index.php/t-73469.html I just wanted everyone to know about this problem in case you run across similar slow "connectivity" issues. I believe the network card is made by NVIDIA.
