DHCP and Static IP needed

I have a Windows XP laptop that connects to my ISP through DHCP. The
problem is that I also have another computer (Windows 98) which also
connects to the ISP through DHCP and is always assigned an IP in a different
subnet. I want both computers to also see each other for file sharing and
remoting, so how can I do this?

I was able to add a second TCP/IP connection on the Win98 machine and gave
it an IP of 10.0.0.100. However, there doesn't seem to be any way to do the
same thing in WinXP. I cannot add another network connection, and I cannot
add another TCP/IP address if the connection is using DHCP. If I try to add
another protocol, it doesn't show TCP/IP as a choice.

You're right: it isn't possible to assign both a DHCP address and a
static address to a network connection in Windows XP.

From your description, I'm assuming that you get two IP addresses from
a broadband (cable modem or DSL) ISP. Please forgive me if that's not
right.

There's no way to ensure that the IP addresses that you get from the
ISP will be in the same subnet. As a result, your computers can't
communicate with each other using TCP/IP.

The solution is to install a different protocol on both computers, use
it for file and printer sharing, and un-bind file and printer sharing
from TCP/IP. I've written a web page with details:

A completely different alternative would be to get a broadband router
to share a single IP address between the computers.
