Not that I know of. You can see this MS Article about troubleshooting 
network problems
http://www.microsoft.com/technet/winnt/winntas/Tips/techrep/network.asp

You can also run the "winipcfg" program from Start -- Run and at least see
the Ethernet card's adapter address. Everything else should be 0 or blank.
Click on OK to quit.
