RDP from Vista slow after Windows 2003 Server SP2 installed

After installing W2K3 SP2 on one of my servers, the RDP session was awfully slow, especially mouse clicks.

It appears that Vista TCP/IP "Receive Window Auto-Tuning " is the culprit.

To disable it, open a command prompt and type:

netsh interface tcp set global rss=disabled
netsh interface tcp set global autotuninglevel=disabled

and reboot .
