hopefully this is the correct forum, new to the PC Review website. I have a networking problem that has got me puzzled. The machines in question are NAS device and Host server. The NAS is running W2k terminal and HOST is running w2k3 64bit. Both have gigabit ethernets. Networking is working fine between the machines (no network just hard connected together with cross over cable) If I copy from HOST to NAS all seems great for the first 100MB but after that the network speed drops considerably. On the HOST in task manager -> network tab I see the % reduce from 30 to 0 then .55 etc. I saw in another posting the duplex setting sometimes does not work if set to "AUTO", however that posting was referencing a hub between machines. I have not hub, just directly connected. Any help is most appreciated. TCMLEAD
