Understanding Resource Dependencies
Before an Exchange resource can be brought online, there are frequently other Exchange resources that must be brought online before it. This requirement is known as a resource dependency.
The Resource dependencies list on a specific Exchange resource object lists the other resources that must be brought online before this resource can be brought online. The following table lists the Exchange 2003 cluster resources and their default dependencies.
