Have you uninstalled the drivers as per this thread:

Also, might be worth checking that your network adaptor is enabled.
Go to:
Start > Control Panel > Network Connections
Right click on the icon for your ethernet adaptor and see if there is an option that says "enable" if there is then you should select this option.
