Is the Windows box set up as a gateway, with Internet Connection Sharing
enabled? If not, you won't get DHCP, it won't route to the Internet,
etc.

What are your goals with this network? Do you want the Linux box to be a
router for your Internet access? Do you want it to go through the XP box
for 'net access? What do you want to do with the network?

Thanks for taking the time to post with some informative details. It's
much appreciated.

That's normal, since /etc/resolv.conf won't have any DNS servers in it.
Additionally, you have no default route, so even if the system did have
some DNS servers set up it wouldn't know how to access them.

You've asked the DNS server on 192.168.0.1 to resolve ubuntu.com . Since
you almost certainly don't have a DNS server on 192.168.0.1 that won't
do any good.

The `ifconfig' command configures the interface at runtime. It doesn't
save settings anywhere, so when you reboot the settings revert to
normal. You would have to configure your system to use a static IP
address if you wanted it to persist.

Alas, this is not as simple as `ifconfig --save'. Others have explained
the details for this configuration.
