We are running Exchange 2003 and Exchange 2007.
Our Exchange 2003 servers are all Active/Active/Passive clusters running Windows 2003.
Our Exchange 2007 servers are SCC Active/Passive running Windows 2008.
With 2003, there is a cluster namednamed CLUSTER RESOURCE that contains the Quorom etc plus another cluster group containing the Exchange specific resources With Exchange 2007, the only cluster resource is the CMS.
Does anyone know if there is an actual reason for this (difference in number of nodes, difference in OS etc), or should we have added another Cluster Resource when we built the 2007 servers for the Quorum?
