TheRecovery Console is a feature of theWindows 2000,[1]Windows XP[2] andWindows Server 2003 operating systems. It provides the means for administrators to perform a limited range of tasks using acommand-line interface.

Its primary function is to enable administrators to recover from situations where Windows does notboot as far as presenting itsgraphical user interface. The recovery console is used to provide a way to access the hard drive in an emergency through the command prompt. The Recovery Console can be started fromWindows 2000 / XP / 2003 Setup CD.

The Recovery Console can be accessed in two ways, either through the original installation media used to install Windows, or by installing it onto the hard drive and adding it to theNTLDR menu. However, the latter option is much more risky than the former one because it requires that the computer can boot to the point that NTLDR loads, or else the Recovery Console will not work at all.[3]

Abilities

[edit]

The Recovery Console has a simplecommand-line interpreter (or CLI). Many of the availablecommands closely resemble the commands that are normally available incmd.exe, namelyattrib,copy,del, and so forth.

From the Recovery Console an administrator can:

  • create and remove directories, and copy, erase, display, andrename files
  • enable and disable services (which modifies the service control database in the registry, to take effect when the system is next bootstrapped)
  • repair boot file, using thebootcfg command
  • write a newmaster boot record to a disk, using thefixmbr command
  • write a newvolume boot record to a volume, using thefixboot command
  • format volumes
  • expand files from the compressed format in which they are stored on the installationCD-ROM
  • perform a fullchkdsk scan to repair corrupted disks and files, especially if the computer cannot be started properly

Filesystem access on the Recovery Console is by default severely limited. An administrator using the Recovery Console has only read-only access to all volumes except for theboot volume, and even on the boot volume only access to the root directory and to the Windows system directory (e.g. \WINNT). This can be changed by changing Security Policies to enable read/write access to the complete file system including copying files from removable media (i.e. floppy drives).

Commands

[edit]

The following is a list of the Recovery Consoleinternal commands:[1][2]

Although it appears in the list of commands available by using thehelp command, and in many articles about the Recovery Console (including those authored by Microsoft), thenet command is not available. No protocol stacks are loaded, so there is no way to connect to ashared folder on a remote computer as implied.
