IMSAdminBase::Restore

The IMSAdminBase::Restore method restores the metabase from a backup. The restore operation stops all services dependent on IISADMIN, including all servers, until the restore has completed, then restarts all services. You should plan for this service interruption when restoring the metabase from a backup.
