Cluster continuous replication (CCR) on Windows Server 2003 requires a quorum model called the Majority Node Set (MNS) quorum with file share witness. This quorum model is available in Windows Server 2003 Service Pack 2 (SP2), which is required for Microsoft Exchange Server 2007 Service Pack 1 (SP1).
To use the MNS quorum with file share witness with the release to manufacturing (RTM) version of Exchange Server 2007 and Windows Server 2003 SP1, you must install the hotfix described in Microsoft Knowledge Base article 921181, An update is available that adds a file share witness feature and a configurable cluster heartbeats feature to Microsoft Windows Server 2003 Service Pack 1-based server clusters. The hotfix must be installed onto each node prior to deploying CCR.
|This procedure should be performed only on computers running Windows Server 2003 SP1.|
Before You Begin
