Using Cluster Administrator to Manage Exchange Clusters
As with standard Windows clusters, you perform most of the configuration tasks, and also the management tasks, associated with Exchange clusters using Cluster Administrator. Cluster Administrator is installed by default on servers that have Cluster Service installed and are running one of the following operating systems: Microsoft Windows Server 2003, Microsoft Windows 2000, or Microsoft Windows NT® 4.0 Service Pack 3 (or later).
You can also use Cluster Administrator to remotely administer a server cluster. Computers that are used to administer a server cluster remotely must be secure and restricted to trusted personnel. For more information, see "Best practices for securing server clusters" in the Windows Server 2003 Enterprise Edition Online Help. For detailed instructions, see How to Open Cluster Administrator.
