How to Improve Terminal Server Sessions
The Terminal Services feature on Windows Server 2003 works much like the Remote Desktop feature on newer versions of Windows, allowing you to access a computer's desktop remotely from another computer. Sometimes while using Terminal Services, you may notice that it is running a bit slow. To speed up the performance of Terminal Services, there are several edits to the registry that you can make. You do not have to make all of the edits but making even a few of them will increase the speed of your Terminal Services utility.
