I got four different PCs here with Windows7 RTM x64 on them. Between these PCs the network is benching around 600-700Mbit/s. So it's quite decent on my Gigabit network. But if I try to access my Windows Server 2003 R2 from any of these Win7 PCs I only end up getting around 100-120Mbit/s of speed, which is horrible slow. If I boot up XP on any of these PCs and attempt to access the server again I bench around 600-700Mbit/s. which is normal once again. Anyone else got this weird symptom? All my Win7 PCs are running on different motherboards and they are all x64. They are all using the included Network drivers which are all WHQL-certified as they are all signed by Microsoft. I have already tried disabling the TCP Scaling.
