In fact, it is possible to completely rebuild a failed Exchange Server from scratch aside from the mailbox database simply by making use of the configuration data that is stored in the Active Directory.

So with that in mind, imagine that a trust relationship was accidentally broken and you decided to fix the problem by deleting the Exchange Server's computer account and rejoining the computer to the domain.
