[This topic is intended to address a specific issue called out by the Exchange Server Analyzer Tool. You should apply it only to systems that have had the Exchange Server Analyzer Tool run against them and are experiencing that specific issue. The Exchange Server Analyzer Tool, available as a free download, remotely collects configuration data from each server in the topology and automatically analyzes the data.

Microsoft Exchange Server 2007 Disaster Recovery cannot continue because a different version of Exchange Server 2007 was originally used to install Exchange Server on this computer.
Microsoft Exchange Disaster Recovery requires that the version of Exchange Server 2007 used to perform a recovery of the Exchange Server match the version that was originally used to install the Exchange Server.
To resolve this issue, start Exchange Server 2007 Disaster Recovery from the same version of Exchange Server 2007 that was originally used to install the Exchange Server.
The Exchange Server 2007 RTM build version number is 685.25. When you view the version in the Exchange Management Console or in the AdminDisplayVersion property of Exchange Server in the Exchange Management Shell, they show the version as 685.24 instead of 685.25. When you view the Exchange version in the Registry, it shows 685.25. In addition, the Microsoft Operations Manager (MOM) shows the Exchange servers as 685.25. Outlook indicates that you're connected to 685.24. These inconstancies are by design and can be ignored.
