Title: 70291: MCSE Guide to Managing a Microsoft Windows Server 2003 Network, Enhanced Chapter 14: Troubles


1
70-291 MCSE Guide to Managing a Microsoft
Windows Server 2003 Network, Enhanced Chapter
14 Troubleshooting Windows Server 2003 Networks
2
Objectives
  • Outline the maintenance cycle
  • Understand common troubleshooting methodology
  • Use common Windows Server 2003 tools to
    troubleshoot server and network problems
  • Describe the common network connectivity
    problems and their solutions

3
Troubleshooting Methodology
  • Maintaining system integrity includes monitoring,
    proactive maintenance, and reactive maintenance
  • Monitoring examining network connectivity,
    viewing log files and running performance
    utilities periodically
  • Proactive maintenance taking the necessary steps
    to minimize the chance of future problems
  • Reactive maintenance to correct problems when
    they arise during monitoring

4
Troubleshooting Methodology (continued)
  • Reactive maintenance composed of many procedures
    known as troubleshooting procedures
  • Two golden rules that should guide you during any
    troubleshooting process
  • Prioritize problems
  • Try to solve the root of the problem

5
Troubleshooting Methodology (continued)
6
Troubleshooting Methodology (continued)
7
Troubleshooting Tools
  • Most common tools include
  • Network Monitor
  • System Monitor
  • Performance Logs and Alerts
  • Event Viewer
  • Task Manager
  • Services snap-in

8
Network Monitor
  • Used to view and log network activity
  • Two main components
  • Network Monitor
  • Network Monitor driver
  • Version of Network Monitor included with Windows
    Server 2003 is only designed to capture data at
    the computers local network interface

9
Activity 14-1 Installing Network Monitor
  • Objective Install Network Monitor

  • Make sure Network Monitor driver is installed

10
Activity 14-2 Using Network Monitor
  • Objective Use Network Monitor to monitor traffic
    on a network
  • Start Network Monitor
  • Press F10 to start capturing performance data
  • Ping some IP address
  • Press F11 to stop capturing and press F12 to
    display captured data

11
Activity 14-3 Creating a Filter in Network
Monitor
  • Objective Create a filter in Network Monitor
  • Start Network Monitor
  • Press F8 to configure filter
  • Press F10 to start new capture

12
System Monitor
  • One of the most useful tools for collecting data
    on real-time server performance
  • Collects data that you can use for the following
    tasks
  • Server performance
  • Problem diagnosis
  • Capacity planning
  • Testing
  • Information captured can be displayed with a
  • Graph
  • Histogram
  • Report

13
System Monitor (continued)
14
Activity 14-4 Exploring System Monitor Settings
  • Objective Explore Windows Server 2003 System
    Monitor settings
  • View data in histogram, report, and graph mode
  • Highlight counters
  • Freeze the display
  • Try out the Update Data button

15
Activity 14-5 Adding Counters to System Monitor
  • Objective Add object counters to the System
    Monitor tool
  • Start System Monitor
  • Select PhysicalDisk performance object and add
    Disk Read Time counter
  • Select Memory object and add Available MBytes
    counter
  • Add all counters

16
Activity 14-6 Saving and Viewing System Monitor
Data
  • Objective Explore options for saving System
    Monitor data
  • Start System Monitor
  • Collect data and freeze the display
  • Save data as htm file

17
Performance Logs and Alerts
  • Allows for the automatic collection of data on
    the local computer or from another computer on
    the network
  • Allows you to perform the following tasks
  • Collect data in binary, comma-separated, or
    tab-separated format
  • View data while being collected and after
    collection
  • Configure and manage multiple logging sessions
    from a single console window
  • Set up alerts

18
Performance Logs and Alerts (continued)
  • Three options available
  • Counter logs
  • Trace Logs
  • Alerts
  • Counter logs take information from System Monitor
    and save it to a log file
  • Trace logs are triggered to start when an event
    occurs
  • Alerts are used to configure an event to occur
    when a counter meets a predefined value

19
Performance Logs and Alerts (continued)
20
Performance Logs and Alerts (continued)
21
Activity 14-7 Configuring Performance Logs and
Alerts
  • Objective Configure performance logging and
    alerts
  • Right-click System Overview icon and click start
  • Wait 2 minutes, click stop, and then use System
    Monitor to view log file
  • Set alerter service and messenger service to
    automatic
  • Configure an alert to send a network message
    according to the instructions

22
Event Viewer
  • Most common and effective monitoring and
    troubleshooting tool
  • Used to gather information and troubleshoot
    services, hardware, and system problems
  • Three log files
  • Application log
  • Security log
  • System log
  • The system log can only be viewed by
    administrators and those users with appropriate
    permissions

23
Event Viewer (continued)
24
Event Viewer (continued)
25
Activity 14-8 Viewing Event Viewer System and
Application Log Events
  • Objective View events in the Event Viewer system
    and application logs
  • Open Event Viewer
  • View contents of application log
  • View the contents of the system log

26
Task Manager
  • Provides one of the fastest ways to check server
    and network performance and to determine what
    processes are running on the system
  • Consists of five different tabs
  • Applications
  • Processes
  • Performance
  • Networking
  • Users

27

    system performance data
  • Press CtrlAltDelete
  • End some processes
  • Change some priorities
  • Review performance data

30
Services Snap-in
  • Always disable any unnecessary components such as
    services

35
Troubleshooting Network Connectivity
  • Requires a broad knowledge of several network
    concepts in order to solve a problem
  • Common problems include
  • Computer cannot access resources on the local
    network
  • Computer cannot access the Internet or a remote
    network but can communicate locally
  • A computer cannot access resources on the local
    network using name resolution
  • A computer cannot access remote resources

36
Summary
  • Network administrators monitor the network and
    servers on a regular basis and perform proactive
    and reactive maintenances
  • Common troubleshooting procedures involve
  • Collecting data to determine the cause of system
    problems
  • Implementing and testing solutions
  • Network Monitor gathers information about network
    performance
  • The Performance console uses System Monitor and
    Performance Logs and Alerts to monitor server
    health

37
Summary (continued)
  • You can configure alerts for specific objects and
    counters
  • You can use Event Viewer to view the contents of
    the system logs, application logs, and security
    logs
  • Task Manager provides information on processes
    and applications running on a system
  • When optimizing the performance of your computer,
    use the Services icon to disable any unnecessary
    services to eliminate overhead
