The cause of the problem is due to advanced network functions in Vista that attempts to tune the network configurations to optimize network transfer speed and make full use of available bandwidth.問題的原因是由於先進的網絡功能在Vista中企圖以調整網絡配置，優化網絡傳輸速度並充分利用可用帶寬。

Thus the solution to the Remote Desktop Connection slow issue after installing SP2 in 64-bit Windows Server 2003 is easy.因此，解決遠端桌面連線緩慢的問題後，再安裝SP2在64位Windows Server 2003的過程非常簡單。 It’s by turning off and disabling these network settings.它的關閉和禁用這些網絡設置。

There are 2 settings that may affect network tuning - autotuninglevel for有2個設置，可能會影響網絡的調整-a utotuninglevel為 Receive Window Auto-Tuning Level接收窗口自動調諧水平 which continually determines the optimal receive window size by measuring the bandwidth-delay product and the application retrieve rate, and adjusts the maximum receive window size based on changing network conditions, and rss for不斷確定最優接收窗口大小通過測量帶寬時延產品和應用檢索率，並調整，最高可接收窗口大小的基礎上不斷變化的網絡條件，和RSS為 Receive-Side Scaling State接收方結垢國家 which allow the network load from a network adapter to be balanced across multiple CPUs.使網絡負載從一個網絡適配器，以平衡全國多個CPU 。

It’s best to disable these 2 settings for resolution.它的最佳停用這些2設置的決議。 However in most cases, disable autotuninglevel alone will solve most network problems.但在大多數情況下，禁用autotuninglevel僅將解決大部分的網絡問題。 To disable these network tuning functions,禁用這些網絡微調功能， open elevated command prompt with administrator rights開放提升的命令提示符具有管理員權限 , the type the following commands: ，鍵入以下命令：

netsh interface tcp set global rss=disabled在netsh界面的TCP設置全球的RSS =禁用
netsh interface tcp set global autotuninglevel=disabled在netsh界面的TCP設置全球autotuninglevel =禁用

Or if you want to combine them into single command, use the following:或者，如果您想結合起來，他們成為單一命令，使用下列內容：

netsh interface tcp set global rss=disabled autotuninglevel=disabled在netsh界面的TCP設置全球的RSS =禁用autotuninglevel =禁用

Reboot the computer after the operation completed.重新啟動計算機，手術後完成。 The RDP connection should work faster now.該RDP的連接，應加快工作現在。
