home network wont ping across connection

[wayne6707]

Hi

I have set up a small 2 computer network using windows xp for a friend which was working correctly for a couple of days. However it then suddenly stopped working. It became apparant that windows was reporting the cable as unplugged however it was plugged in as normal (cat5e crossover cable). I immediately acquired a new cable and tried that which failed to work. Since then i have made a ethernet loop back plug by crossing over the tx and rx pairs and found out that one of the computers dosent respond to it at all. I then tested the network card by pinging 127.0.0.1 which passed. I decided to reinstall the network card on this computer and i am now in a state where both computers now say connected after i changed them to use 100Mbps instead of auto detect and i have static ip addresses set on each of them. However when i attempt to ping both of them respond differantly. One says destination host unreachable and the other says request timed out. I have disabled all firewalls on both computers and still i recieve the same response i have even tried using two straight through cables and a hub but i get the same response. Does anyone have any ideas why this might be failing.

take a hub, 2 straight cable, 2 ethernet adaptor in the main pc and one ethernet adaptor in the second pc, provide internet connection in one ethernet adaptor of the main pc, and from the second adaptor connect it to the hub, also connect the second pc to the hub with the help of straight cable, now provide the following setting's in the second pc,
ip=192.168.0.2
sub=255.255.255.0
D.Gateway=192.168.0.1
DNS=192.168.0.1

switch off the firewall of both the pc's

Then share the internet of the ethernet adaptor having internet connection, I mean the main pc, don't change any settings of the second ethernet adaptor of the main pc the ip to the second ethernet adoptor will be given automatically

this will work i am sure as I have already done this atleast 100 times

i like your answer but it seems i didnt quite put all the detail into the post. First it is too laptops so using additional adaptors is out of the question at the moment and they are only being used for a lan to play games on not for an internet connection.
