Sorry for the dumb question I am pretty good in the Microsoft world but I'm working on making the switch. I am installing 10.2 and I get to my network connection setup. I leave the domain and host whatever it was defaulted to and it fails to connect. It picks up the nic card and I am just using a dhcp cable connection through a router. Nothing special. I haven't even gotten into linux yet, but my connection should be pretty simple what am I missing?

error dhcp client is already running on eth0

please help
