 Have you checked that the Link LED of the NIC is lit?

I have two machines with the NVIDIA MCP chipset and the Marvell MAC (One
windows and one Linux) which have this problem.  The problem is usually
experienced when the power cable has been unplugged on the computer or the
switch.  The resolution seems to be as follows:

1) Shutdown the computer
2) Remove power cable
3) Remove ethernet cable
4) Wait 2 minutes
5) Plug in power cable
6) Startup the computer
7) Plug in the power cable - After the computer has fully started, IE the
GUI is visible.
