I have two computers with Windows 7 64 bit set up as part of a Homegroup. I can see the computers from each machine and even browse files/directories. However, when I try to cut and paste or drag-n-drop files from one machine to another one machine freezes and requires the reset button to restart the machine. It is only one machine that freezes, but it consistently freezes every time I attempt a file transfer. The computer that freezes is connected wirelessly to the network. The other computer is wired to the router. I am stumped. I have tried all new drivers, latest bios, etc. Anyone able to help me?
