Hey everybody, Thanks in advance for the help - I rarely post questions unless I've exhausted all other means. Here's the problem... on my Mac Pro v1,1 network connectivity is just fine over gigabit either-net. The trouble starts when I boot into windows 7 pro (64bit) to play a game. Networking starts out fine, and then intermittently drops, as if I don't even have an ip address. It wont connect until I force it to renew the DHCP lease or unplug the cable and re-plug it in again. This is only on Windows 7. Life is good on the macos side. Has anyone ever seen this or have a fix for it?
