Installing Microsoft Windows 2000 Server and Small Business Server 2000
Tip #4. Windows 2000 Recovery Options
In the event that the current installation of Windows 2000 fails to boot (this might
happen after installing a new driver, component, software, etc), Windows 2000
provides the following recovery options to help you gain access to your Windows
2000 installation to replace damaged files and services for troubleshooting purpose.
HP therefore recommends that you install the Recovery Console (refer to option 3
below) to enhance the system configuration.
Recovery option #1: Last Known Good Configuration
Activated by pressing the F8 key during the system process of Windows 2000
and selecting Last Known Good Configuration from the menu.
This boot mode is used in the case that the system fails to boot after installing a
new software or driver. The system will use the previous registry setting to
initialize and boot the system.
Recovery option #2: Safe Mode Boot
This is activated by pressing the F8 key during the OS boot. It provides a minimal
configuration with required drivers and services. The safe mode boot provides three
options:
Standard safe mode boot – provides no network services or drivers.
Networking disabled – excludes network services and drivers.
Directory services restore mode – brings system up with directory services
disabled with the intent of recovering active directory. Safe mode boot is guided
by the registry key hklm\CurrentControlSet\Control\SafeBoot with the use of the
Minimal and Network subkeys. The IO Manager and Service Control Manager
look at the registry to load the driver and services. Such approach avoids loading
a problematic driver or service.
Command prompt – provides an alternate command shell CMD.EXE instead of
the explorer. This is dictated by the registry key:
hklm\system\CurrentControlSet\Control\SafeBoot\AlternateShell
