Managing Hardware Devices and Drivers• Hardware includes any devices that were connected to
your computer when it was manufactured, as well as peripheral equipment added later.
• Some devices are connected to expansion slots inside the computer.
• Some devices are connected to ports on the outside of the computer.
• Each device has its own unique device driver.
Hardware Types• Microsoft Windows 2000 classifies devices by hardware
type.• Hardware types include individual devices.• Devices can be classified according to how they connect
to your computer.• Devices can include several types of hardware.• The Windows Hardware Compatibility List (HCL) lists
Windows 2000–supported devices.
Plug and Play• Adheres to a set of specifications developed by the IEEE
and computer and software manufacturers• Allows a computer to automatically detect and configure
a device and install the appropriate device drivers• Works with the Windows 2000 Power Options utility to
manage the power requirements of your hardware and peripherals
Installing Devices• Connecting the device to your computer• Loading the appropriate device drivers for the device• Configuring device properties and settings
Uninstalling Devices• You can usually uninstall Plug and Play devices by
disconnecting them or removing them.• You should notify Windows 2000 when uninstalling non–
Plug and Play devices.• You can disable a Plug and Play device rather than
uninstall it.

Event Logs• The System log can help you predict and identify the
sources of system problems.• The Application log and System log can help you confirm
problems with software.• Follow certain guidelines when you use event logs to
diagnose problems.
Installing Service Packs• Windows 2000 makes it easier for administrators to add
service packs.• Windows 2000 supports service pack slipstreaming.• Windows 2000 eliminates the need to reinstall
components applied before a service pack was installed.
Service Pack Slipstreaming• Service pack slipstreaming refers to a service pack being
applied to Windows 2000 distribution files.• To apply a new service pack, use Update.exe with the
/slip switch.• Windows 2000 replaces several key files.
Post-Setup Installation of a Service Pack• A service pack is applied on an existing Windows 2000
system by running Update.exe.• If the system state changes, Windows 2000 installs the
correct files, whether those files originate from the Windows 2000 installation CD‑ROM or from the service pack.
Introduction to Windows Backup
Planning for Windows Backup• Determine which files and folders to back up.• Determine how often to back up.• Determine which target media to use for storing backup
data.• Determine whether to perform network or local backup
jobs.
Setting Backup Options
Backup Types
Setting Backup Types for Specific Jobs
Combining Backup Types• Normal and differential backups• Normal and incremental backups• Normal, differential, and copy backups
Performing Preliminary Tasks• Before each backup job, ensure that the files to be
backed up are closed.• If you use a removable media device, make sure that
several preliminary tasks are completed.
Selecting Files and Folders to Back Up
Specifying Backup Destination and Media Settings• You must provide information for the backup media
options.• You must start the backup or specify advanced backup
options.
Specifying Advanced Backup Settings• When you specify advanced backup options, you are
changing the default backup settings for the current backup job.
• You can configure a number of advanced options.• You can choose to back up now or later.
Scheduling Backup Jobs• A scheduled backup job occurs at a later time and is
unattended.• Windows Backup is integrated with the Task Scheduler
service.• Click the Later radio button on the When To Back Up
screen of the Backup Wizard.• The job is placed on the Windows Backup calendar.
Overview of UPS• Disaster recovery is the restoration of a computer so
that you can log on and access system resources after a disaster has occurred.
• An uninterruptible power supply (UPS) provides power if the local power fails.
• A UPS is usually rated to provide a specific amount of power for a specific period of time.
Configuring Options for UPS• Use the UPS tab of the Power Options Properties dialog
box to configure the UPS service.• You must specify the COM port, the conditions that
trigger the UPS device, and the time intervals for battery settings.
Testing a UPS Configuration• You should test the UPS configuration to ensure that
your computer is protected from power failures.• You should not use a production computer to test the
UPS configuration.• You should wait until the UPS battery reaches a low level
to verify that an orderly shutdown occurs.
Implementing Disk Fault Tolerance• Fault tolerance is the ability of a computer or operating
system to respond to a catastrophic event so that no data is lost or corrupted.
• Disk fault tolerance is not an alternative to a backup strategy.
Implementing RAID (Redundant Array of Independent Disks)
• Software implementations• Hardware implementations
Mirrored Volumes
RAID-5 Volumes
Mirrored Volumes vs. RAID-5 Volumes• Mirrored volumes and RAID-5 volumes provide different
levels of fault tolerance.• Mirrored volumes offer read and write performance
comparable to a single disk.• Disk utilization improves with RAID 5.
Implementing RAID Systems
Safe Mode• Safe Mode• Safe Mode With Networking• Safe Mode With Command Prompt• Enable Boot Logging• Enable VGA Mode• Last Known Good Configuration• Directory Service Restore Mode• Debugging Mode
Recovery Console• The Recovery Console is a text-mode command
interpreter that is separate from the Windows 2000 command prompt.
• The Recovery Console allows you to gain access to the hard disk of a Windows 2000 computer.
• You can obtain limited access to NTFS and FAT volumes.• To start the Recovery Console, start the computer from
the Windows 2000 installation CD‑ROM or the Windows 2000 Setup floppy disks.
Emergency Repair Disk (ERD)• Windows Backup includes a wizard to help you create
the ERD.• You should create an ERD when your computer is
functioning properly.• The Windows 2000 ERD does not contain a copy of the
registry files.• The backup registry files are in the %systemroot%\
Repair folder.
Preparing to Restore Data• Base your restore strategy on the backup type you used
for the backup.• Perform a trial restore periodically to verify that
Windows Backup is backing up your files correctly.• Keep documentation for each backup job.• Keep a record of multiple backup jobs in a calendar
format.
Selecting Backup Sets, Files, and Folders to Restore• The first step in restoring data is to select the data to
restore.• Use the Restore wizard to restore data.• After you run the Restore wizard, you can finish the
restore process or specify advanced restore options.
Specifying Advanced Restore Settings• The advanced settings in the Restore wizard vary.• After you have finished the Restore wizard, Windows
Backup takes specific actions.• You can configure a number of restore options.
Recovering from a Mirrored Volume Failure
Repairing a RAID-5 Volume• Replace the failed drive, and then repair the RAID-5
volume. • The fault tolerance driver reads the parity information
stripes on the remaining members, and then re-creates the data contained on the missing member.
