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
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.
