Emergency Move


If your domain controller (DC) has failed and is not bootable you can use the following emergency procedure to quickly restore Active Directory on the original computer or recover it on a new computer.

The following are quick instructions for emergencies only. For a planned upgrade to a new computer see Planned Move.

Important: Do not purchase a license for U-Move until after you have completed step 5 successfully.
Step 1: Restore from a Volume Shadow Copy (if available), or...

If you have a Volume Shadow Copy (VSC) snapshot image of the C: disk available, you might be able to recover Active Directory from the volume snapshot. Boot DSRM if needed to log on, then run U-Move.

Click on the tab Restore. For the location of the AD files click on Volume Shadow Copy on a local disk, select disk C:, and go to step 5. Otherwise proceed to step 2.

Step 2: Get the most recent backup copy

Find the most recent image of the C: disk. Use either the original disk or a backup created with Windows Server Backup. Connect the backup disk to the new computer if necessary.

If you used Windows Server Backup to create compressed DVD disks, use a utility such as U-Recover to expand and mount the DVD disk image(s). If you used a third-party backup utility, restore a temporary copy of the C: disk image to an empty disk volume with a temporary disk letter (for example E:).

Do not use a System State backup. A System State backup is not sufficient for moving AD to a new computer.

If you have no backup of the C: disk available, you might be able to salvage Active Directory by copying the database files directly off an image of the dead computer's original C: disk. See Copying from a Dead Computer.
