Following are the hardware requirements to run an NLB cluster. All hosts in the cluster must reside on the same subnet. There is no restriction on the number of network adapters on each host, and different hosts can have a different number of adapters. Within each cluster, all network adapters must be either multicast or unicast. NLB does not support a mixed environment of multicast and unicast within a single cluster. If you use the unicast mode, the network adapter that is used to handle client-to-cluster traffic must support changing its media access control (MAC) address. Following are the software requirements to run an NLB cluster. Only TCP/IP can be used on the adapter for which NLB is enabled on each host. Do not add any other protocols (for example, IPX) to this adapter. The IP addresses of the servers in the cluster must be static.
