Single NIC install of Edubuntu

[David Trask]

What I'm running into are a few things...and I'm sure I'm just missing
something.  First...I've disabled the other onboard NIC on the
server....it doesn't get and address, but ifconfig still shows it's there.
 I also need to change the default addressing scheme for DHCP to a
10.0.0.x network.  I did that and it seemed to break something so that the
thin-clients don't finish booting....they get the Edubuntu splash screen,
but end with an initramfs message.  I haven't gotten into it too far...so
I have not troubleshot that issue.  Nonetheless, I'm also able to ping,
but unable to resolve.  In other words....ping 10.0.0.1  works fine
(10.0.0.1 is my firewall/router for the LAN)...yet ping abc.com
doesn't...nor does firefox go to any web sites (although it will go to IP
addresses)....so I'm guessing it's not resolving.  So...what do I need to
change and watch out for when changing the network addressing from the
default 192.168.x.x to 10.0.x.x.  I'm pretty sure I had most
everything...the server has the right address....

Not 100% sure where everything lives now.  Thought about editing
/etc/resolv.conf manually, but it doesn't seem like anything is in there

Any ideas welcome
