The Messaging Server is the third server installed as part of a core Windows Essential Business Server 2008 deployment. Its duties include messaging and collaboration for the Windows Essential Business Server 2008 solution. For network infrastructure redundancy, the Messaging Server also acts as an additional domain controller for the domain. It also acts as a second DNS server.
Our customers told us over and over again that email is king. Here you see an isolated mail environment and it's supporting services.

Also it's worth mentioning how all of these services are managed as part of the Unified Administration of Essential Business Server. Watch this space as we're planning to dive into much more detail on this soon.
