Communication across a network is increasingly important in the work environment. Similar to processors or disks on your system, the behavior of the network has an impact on the operation of your computer. In this chapter, you will learn how to optimize your system's performance by analyzing network performance such as monitoring network traffic and resource utilization. Microsoft Windows 2000 provides two primary utilities for monitoring network performance: System Monitor and Network Monitor. System Monitor, installed with both Windows 2000 Professional and Windows 2000 Server, tracks resource utilization and network throughput. Network Monitor, an optional component for Windows 2000 Server, tracks network throughput in terms of captured network traffic. This chapter focuses on using Network Monitor to examine local traffic.
This Tutorial is divided into three sections:
INTRODUCING NETWORK MONITOR
You can use Microsoft Windows 2000 Network Monitor to view and detect problems on local area networks (LANs). For example, you can use Network Monitor to diagnose hardware and software problems when two or more computers cannot communicate. You can also copy a log of network activity into a file and then send the file to a professional network analyst or support organization. In addition, network application developers can use Network Monitor to monitor and debug network applications as they are developed.
USING NETWORK MONITOR
Network Monitor monitors the network data stream, which consists of all information transferred over a network at any given time. You can use a display filter to determine which frames to display. To design a capture filter, specify decision statements in the Capture Filter dialog box. After you have captured data, you can view it in the Network Monitor user interface. Make sure you specify a capture buffer large enough to accommodate the traffic you need.
WINDOWS 2000 ADMINISTRATION TOOLS
SNMP is a network-management protocol widely used in TCP/IP networks. It can be used to communicate between a management program run by an administrator and the network-management agent running on a host or gateway. You can also use SNMP to monitor and control remote hosts and gateways on an internetwork. The Windows 2000 SNMP service allows a Windows 2000 computer to be monitored remotely. The SNMP service can handle requests from one or more hosts, and it can also report network-management information to one or more hosts, in discrete blocks of data called traps. When you install the SNMP service, TCP/IP performance counters become available in Performance Monitor.
