I just bought myself a new stunning laptop. The fun is already over because i can't make it transfer al the gigabytes from my old computer to the new one. I plugged in a router, connected both computers with a lan cable, i've set up a network mshome, on both computers. The old one gets into mshome, the onther one says 'not able to enter mshome. You do not have permission... '. I've tried about everything, i can't connect them direct to eachother too. How do i do it? Both have XP Home.
