I have a customer have the problem for Intel 915 GUX
When they trying to connect to their network the onboard NIC is sending a Mac
>address of 0C:00:00:00:00:00 to the switch. The switch doesn't
>recognise the Mac address and shuts down the port. When they check the Mac
>address from the actual PC the Mac address is reported as
>They can re-enable the port and get the NIC talking, get an IP etc but it
>either drops out without warning or shuts down the port the next time
>the PC is rebooted. They tested all the cables and tried different ports
>on different switches and the problem still persisted.
>All there network gear is CISCO and we are using VMPS.
>The PC asset name is: 0306-49155-TC
>The board is a: Intel D915GUX with Gigabit LAN
