Slow RDP Performance from Vista to Windows Server 2003

I have one Windows Server 2003 box in my environment that connects fine through RDP, but once I start clicking around in the RDP session, the response time is extremely slow even though the processor and memory usage is very low.

I’m not sure why one particular server would cause this problem, but I did some searching today and found in one of the forums which appears to be my solution.

From a command prompt, type:

netsh interface tcp set global autotuninglevel=disabled

This disables the autotuning parameter, which by the way, I have no idea what it does.  More research on that to come.
