Solve the problem of connecting windows 2003 remote desktop with win7 and 2008

The reason is that since vista, Microsoft has added a feature called
“Window Auto-Tuning" in the TCP/IP stack. The purpose of this function is to allow the operating system to dynamically adjust the size of the data window transmitted on the network according to the real-time performance of the network (such as response time), so as to achieve network performance optimization in real time. However, in some cases (specifically, what kind of environment, I don't know at the moment), this feature will make the response of the remote desktop very slow. By setting the autotuninglevel to disabled, you can leave the data window at its default value. If set to highlyrestriected, then it is very conservative to adjust the size of this data window (less than a last resort, or use the default value). The setup command is as follows: netsh interface tcp set global autotuninglevel=disabled (or highlyrestricted).
