Task Manager provides information about processes, memory usage, and processor performance statistics. However, it lacks the logging and alert capabilities of the Performance console and does not provide the breadth of information available from System Monitor counters.

To use Task Manager to monitor a process, click the Task Manager's Processes tab to see a list of processes that are running and information about their performance. Task Manager process tables include all processes that run in their own address space, including all applications and system services.

Exchange 2000 runs two processes you can view using Task Manager: Store.exe and Inetinfo.exe.
Note Even if you have more than one virtual server running on a server, only one instance of Store.exe and Inetinfo.exe exists.

To use Task Manager to see a dynamic overview of system performance, including a graph and numeric display of processor and memory usage, click the Performance tab in the Windows Task Manager dialog box. To graph the percentage of processor time in privileged or kernel mode, on the View menu, click Show Kernel Times. This is a measure of the time that applications take to operate system services. The remaining time, known as user mode, is spent running threads in the application code.

If you use multiprocessor computers, on the View menu, select CPU History, and then view the non-idle time of each processor in a single graph or in separate graphs.
