A. Perform one of the following:

  1. When the DHCP Server service starts, if an error is detected in the database it will automatically restore the backup version

  2. Edit the registry and set HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesDHCPServerParametersRestoreFlag to 1, restart the DHCP Server service, this will restore the backed up version and set RestoreFlag back to the default 0

  3. Stop the DHCP Server service, copy the files from %SystemRoot%System32DhcpBackupJet to %SystemRoot%System32Dhcp and then start the DHCP Server service.
