Performance Monitor, included with Windows NT Workstation and Windows NT Server, is a graphical tool for measuring the performance of Windows NT computers on the network.
Windows 95 includes a similar tool, System Monitor. These tools are used by administrators to identify bottlenecks or potential problems.
You can use Performance Monitor to monitor the activity on any computer on the network that is running either Windows NT Workstation or Windows NT Server. However, Performance Monitor cannot view the activity on a computer running Windows 95. Likewise, System Monitor can be used to monitor the activity on any computer on the network that is running Windows 95, but it will not view the activity on a computer running Windows NT Workstation or Windows NT Server. A network administrator should have access to a computer running Windows 95, in order to use System Monitor, as well as the computer running Windows NT Workstation or Windows NT Server, in order to use Performance Monitor.
