How to Recover a Lost Exchange Server

This topic explains how to recover from a server loss using the /m:RecoverServer switch on the setup command. Almost all the settings for a computer running

Microsoft Exchange Server 2007 are stored in the Active Directory directory service. The /m:RecoverServer switch rebuilds an Exchange server with the same name and settings, using the information in Active Directory.

If Setup /m:RecoverServer encounters an error during a server recovery and setup fails, it is possible that running /m:RecoverServer again may also fail. If running Setup /m:RecoverServer again is unsuccessful, you may encounter the following situations:

- Not all server roles are fully recovered.
- Setup fails to recover the remaining roles because the server contains configured roles.
- Uninstalling the remaining roles fails because they failed during disaster recovery efforts, and no other action may be attempted until disaster recovery succeeds.
