The Authoritative Restore tool, AUTHREST.EXE, is used to force a directory database that was
restored from backup to replicate to other servers. It is used in Mixed Mode Exchange
environments that run Exchange 5.5 and the Exchange 2003 Site Replication Service.
AUTHREST.EXE is not new to Exchange 2003 -- it has also been available with all previous
versions of Exchange -- however, it has been updated for use with Exchange 2003.
This tool is generally needed only in a scenario where a directory server containing data
older than the production directory needs to be restored and the missing data must be
backsynchronized to the other production servers. This scenario happens if valid directory
data is accidentally or intentionally deleted. If directory information does go missing from
your organization, you have two choices. If you have a backup of the directory information,
you can restore it and then use AUTHREST.EXE to backsync it (i.e., replicate the missing
data back into the directory). If you don't have a backup, you will need to recreate all of
the data.
For more information on using the updated version of the Authoritative Restore tool, see the
Read Me included with this tool.
