Use the Authoritative Restore tool to force a restored directory database to replicate to other servers after restoring from a backup. It allows you to restore one server (the server with the most recent pre-mistake backup) rather than all servers. With the Authoritative Restore tool, object versions and USNs can be advanced on all writable objects held by that directory so that the data held on the backup appears to be more recent than any copy held by other servers.
You can receive assistance using this tool from Microsoft Product Support Services. This version is the first release on CNET Download.com.
