I have a Windows XP PC connected to the Internet with one NIC and a standard
DSL modem ( this PC was once connected through a router).  When I use
ipconfig I get 2 ip addresses -
10.0.0.12

I have a laptop with a wired nic(fast ethernet) , and a wireless
nic(802.11g). The wireless nic uses WPA to connect.
Both nics connect to the same subnet. Both nics use DHCP to get an IP
address fom a Windows 2003 DHCP Server in that subnet.

Dell computer with an imbedded network adaptor and dial-up modem. I am
getting the error "Network Cable Unplugged". When I use the exact same cable
modem and cable with my laptop it works fine. I have enabled/disabled. I have
uninstalled/reinstalled. It is enabled via BIOS.
