I have two computers running Windows XP on a home network. They are hooked up to a gigabit switch. When moving large video files from one computer to the other, it will move a few files successfully then give me an error that the network connection was lost. The computer that the files are being copied from will then have to be rebooted to continue moving or to even get on the internet (the gigabit switch is hooked up to a wired router). All hardware and software is very current. I tried disabling my AVG firewall on both computers (and of course XP's firewall is off) to no avail.
