Everytime I try to transfer files to my NAS it freezes the computer total lock up only solved by hitting the reset button. Also if I am on another computer and try to take files from it also causes a freeze up. The weird thing is that I can take files from the NAS or other computers on the network no problem. My other computers are Mac's. Do I have something set up wrong in the sharing portion of Vista? It is hard to back up files to my NAS if it freezes everytime I try to.
