2 computer LAN

I'm to connect 2 XP pro computers without a hub using a
cat 5 crossover cable, but get a network cable unplugged
message on both ends. I've checked the cable. What do I
need to do?

In your setup you need to use Internet Connection Sharing (ICS), which is a
feature of W98SE and above. Such a setup requires that one computer be
"Host" and the other computer be "Client". Apparently you have a Network
Interface Card (NIC) installed in each computer, and one computer connected
to the other via the NICs with a Category 5 crossover cable. You also need a
second NIC in your Host computer in order to access the internet. It should
be connected to your modem. Be sure to enable ICS.

Not all network cards support crossover cables. Borrow a hub, switch or
router and connect the two through it with straight network cable. If the
"cable unplugged" message goes away then you won't be able to connect with a
crossover cable.

Are you sure that it's a crossover cable, not a straight cable? How
have you checked it?

To finally respond to all the helpful info;
It's in the network setup wizard that the error message occurs, one has to select "ignore the unplugged cable" or something like that to proceed.

The desktop PC has a USB connection to the DSL modem, I have tried 2 different NIC's in it with both the same response. When I was trying to set up this network previously using a router, the desktop pc seemed to have a spotty time connecting with the router, although it always claims (in Device Manager) that the NIC (either one) is working correctly.

Internet connection sharing has been enabled correctly on both machines when I ran the network wizard (ignoring the unplugged cable.)

The cable I wired myself, with a 586A standard on one end, 586B on the other. I checked the cable with a continuity meter for proper connections and for short circuits. I have wired a number of straight-thru cables in the past with good results, in one case there was an error but I found it with the continuity tester.
Here's the cabling info I used:
586A: 1= white-green, 2= green, 3=white-orange, 4=blue, 5=white-blue, 6=orange, 7=white-brown, 8=brown
586B: 1=white-orange, 2=orange, 3=white-green, 4=blue, 5=white-blue, 6=green, 7=white-brown, 8=brown

A continuity tester can't determine whether a cable will work for
high-frequency Ethernet signals -- it can't tell whether the wire
pairing is right, and it only checks DC continuity.

The cabling info that you used is right. However, since both
computers say that the cable is unplugged, I'm sure that there's a
problem with the cable itself or with the computers' network adapters.

OK, I'll post this here even though its been some
time...it was the cable; I had the connector facing the
wrong way vis-a-vis the diagram I had, which was unclear
(the latch facing towards me instead of away.) It doesn't
matter on a straight cable, but a crossover cable won't
work like that. Thanks again, I finally did what I needed to.

You're welcome. Thanks for reporting the solution. I've made my
share of mistakes in network wiring, so I understand.
