Half of the client computers run Windows XP Professional, and the other half run Windows NT 4.0 Workstation. You install Terminal Server on three member servers named Server1, Server2, and Server3. Each server has a single Pentium III 600-Mhz CPU with 512 MB of RAM and a single-channel EIDE disk subsystem.You place all three terminal servers in an organizational unit (OU) named Terminal Server. You link a Group Policy object (GPO) to the Terminal Server OU. Several days after the installation, users report that the performance of all three terminal servers is unacceptably slow. You discover that each server has at least 50 active sessions at once. You need to improve the performance of all three terminal servers. You must achieve this goal by using theminimum amount of administrative effort, without upgrading any hardware. What should you do? （）
