I have installed Ubuntu Server 12.04 onto my server. As I have no understanding of the Ubuntu Server command line interface - I have installed KDE to aid in setup. (I previously had suse linux enterprise server on the server).

I have two wired network cards in the server - one at eth0, the other at eth1.

eth0 is the one where the internet comes into and is set to Auto DHCP and works fine bringing the internet into the server.

eth1 is the one that connects to my windows box. I have tried to use the settings from the previous suse install - ip address, subnet mask (gateway - what should this be), dns servers & search domains but to no avail - there mut be something I am missing.

The settings are the same as they were on suse, the settings have not changed on the windows box.
