Under Cluster operation mode, click Multicast to specify whether a multicast media access control address is used for cluster operations. If you select this option, Network Load Balancing converts the cluster network address into a multicast address when this is needed. It also makes sure that the cluster Internet Protocol (IP) addresses resolve to this multicast address as part of the Address Resolution Protocol (ARP). The network adapter to which the Network Load Balancing driver is bound retains its original media access control address. For more information, see the "Network Load Balancing clusters" Windows Server 2003 Help and Support Center topic.
