Some users facing a disaster on one of Essential Business Server 2008 servers will naturally attempt to clean the servers' residue from Active Directory before starting a replacement/recovery. This isn’t recommended by EBS and will block recovery solution for EBS Messaging server since EBS relies on preserved computer objects in AD to proceed with replacement and recovery. Without original computer objects, Exchange Server recovery willn’t succeed. Creating new computer objects with same name as original EBS servers isn’t an option and new computer object cannot be used for replacement. More specifically, we’ve seen customers who encounter disaster clean up residue server objects metadata using ntdsutil. Solution: Any object that’s deleted in AD willn’t instantly disappear, it’ll instead remain as a TombStoned object in the "Deleted Objects" container of AD. The object will remain there for tombstone lifetime before it’s permanently removed. The AD tombstone lifetime is set to 180 days in EBS 2008 by default,” EBS blog stated.
