ERD Commander
2000 is the ideal utility for systems administrators
who miss the ease of booting DOS disks to recover
damaged Windows installations. It is a powerful
repair and recovery tool that fixes problems that
prevent Windows NT/2000 from booting, and salvages
systems without losing critical data. Until now,
boot functionality was not a feature available for
Windows NT/2000 even with, in many cases,
the Windows 2000 Recovery Console.
ERD Commander 2000 is a command-line based
utility that boots from either a set of 3.5
floppy disks, a CD-ROM, or directly from the hard
disk of a Windows NT/2000 system. It allows users
to perform recovery-related operations by accessing
and modifying files on NTFS and FAT disk volumes.
ERD Commander 2000s environment mirrors
the standard NT/2000 console-mode environment, so
users familiar with the commands of these operating
systems can intuitively utilize this utility. When
a downed server is booted using ERD Commander
2000, access is provided to every drive and
device available from NT/2000, including removable
drives. Administrators can then remove or replace
corrupted drivers, update system files, correct
security mistakes that prevent the OS from booting,
recover from improperly installed Service Packs
or other updates, and copy essential files off of
a dead system.
ERD Commander 2000 works on NT 4.0 and Windwos
2000.
This read-only version introduces you to the
capabilities of ERD Commander 2000. Most commands
that cause modifications, such as delete, rename,
move, etc., are documented here, but are disabled.
Mkdir and Rmdir are the two modification commands
enabled in this version. Information on
ordering the read/write version of ERD Commander
2000 is available at Winternals Software. |

ERD Commander
can be used to help you solve problems such
as:
Removing or Replacing Buggy Drivers
You can use ERD Commander to delete
the image files of drivers or services that,
because of a bug or misconfiguration, prevent
NT from booting.
Updating Out-of-Date System Files
Incorrectly applying service packs or system
software updates can cause system DLLs to
become out of sync with each other. In many
cases this can prevent NT from booting successfully.
ERD Commander 2000can copy up-to-date
versions of old files from floppy disks or
CD-ROMs onto a system or you can edit files
with its built-in file editor.
Correcting Misconfigured NTFS Security
If security attributes that are too restrictive
are applied to certain system files or directories
on NTFS boot drives, NT will become unbootable.
ERD Commander 20000includes a special
command, Access, which unlocks otherwise inaccessible
files or directories so that NT can access
them.
Updating Locked Files
Once Windows NT/2000 is up-and-running many
system files cannot be replaced because the
system keeps them locked. ERD Commander
2000makes it possible to update such files
because it runs when Windows NT/2000 is off-line
and the files are not open.
Correcting Registry Problems
A number of NT boot problems are the result
of misconfigured Registry values. With ERD
Commander 2000you can edit the Registry
using its built-in Registry editor.
Copying Important Files off of a Dead System
ERD Commander enables you to access
files on an Windows NT/2000 system that fails
to boot. Important files can be salvaged onto
a floppy disk or other removable media.
Note that ERD Commander 2000is not
intended to resolve disk corruption errors,
and that only drives that are consistent enough
to be recognized by Windows NT/2000 file systems
will be accessible with ERD Commander. |
|
Below is a presentation
of what a typical display looks like after
ERD Commander has started. ERD Commander
shows information on the disk drives that
are recognized and the drive letters it has
assigned for them. Volume name, file system
type, and drive size data should help you
identify particular drives.
|
|
When you execute
the ERD Commander 2000 Setup program
it will allow you to create a set of Windows
NT/2000 boot floppies configured with ERD
Commander 2000, create a bootable CD image
of ERD Commander 2000, or install ERD
Commander 2000 to your hard drive as an
alternate Boot.Ini startup option.
When you enter an ERD Commander 2000
installation, a stripped-down version of Windows
NT/2000 will start, and ERD Commander
then starts automatically and enters a command-line
environment nearly identical to the one Windows
NT/2000 implements in Command-Prompt. |
|
The command set
of ERD Commander 2000, like its command-line
editing features, is similar to that of NT.
The command set includes all standard file-related
commands, and virtually all support the same
options as their NT counter-parts. This list
can be obtained inside of ERD Commander
2000by entering the HELP command, and
detailed information on the syntax of a particular
command can listed by typing "command
/?" or "HELP command". Note
that the commands are interpreted in a case-insensitive
manner so that "HELP" is the same
as "help".
Commands colored red are disabled in the read-only
version of ERD Commander 2000.
