Hello guys, I hope you can help me with a problem. I have been trying to link my desktop PC to my Laptop PC with a RJ45 crossover cable. Somewhere down the line I have screwed up, as my desktop now goes into "Not Responding" mode at every opportunity. I removed the Preventon firewall which helped a lot, it is now occasionally freezing. My first question is, can I somehow trace what is causing my PC to not respond? I am assuming that there is a software conflict somewhere down the line. The second question (after I,ve sorted my desktop) is as follows : I have : 1) 1 x desktop PC - XP Pro 2) 1 x Laptop - XP home 3) 1 x RJ45 Crossover cable I want to be able to swap/transfer files between PC's. Can anybody point me in the direction of a step by step process to set up my PC's to talk to each other. Any help is appreciated, Craig.
