I'm trying to install camera software on a friend's XP. Actually, the
camera is outside the house, and there's an intermediate box connected
to the PC by an ethernet cable (crossover). The camera is plugged into
the box. I'm pretty confident that we have the right TCP/IP addresses.

How many physical Ethernet ports does the PC have? Is one of those
ports connected directly to the "intermediate box"? Do the setup
instructions say you should use a crossover cable?

What is the IP address and netmask of the Ethernet port that's
connected to the "intermediate box"? Since the "intermediate box" has
an IP address of 10.0.0.50 it means the directly-connected Ethernet
port on the PC will need an IP address in that subnet, usually with a
netmask of 255.255.255.0, unless a router is in play.

If the PC has a single Ethernet port and it's currently being used for
Internet access, for example, a switch would make sense because it
would allow you to continue using the Internet connection (with the IP
addressing currently configured) while allowing you to set a second IP
address for use with the camera. If you use a switch, however, the
crossover cable should be replaced with a straight cable.
