Vista RTM and its networking "tuning"

I was having some maddening issues with Vista Business RTM:
  • MSN Messenger was constantly getting disconnected, but Google Talk stayed rock solid.
  • LiveMeeting (the Windows version) would not stay connected.
  • Firefox would halfway load a web page and then freeze.
It seems that Vista was automatically tuning my networking settings. Since declining this assistance, the above programs started running normally. The fix for me was to disable network auto tuning:
  1. Click Start and type cmd.
  2. When cmd.exe appears, right click and select Run as Administrator.
  3. Enter the following command: netsh int tcp set global autotuninglevel=disabled
  4. Reboot after getting the OK message.
