IP confict between to machines in the same cluster

I have two machines in a cluster.  There is a unique IP set for each machine for the front end and backend networks.  There is a frount end IP set for the cluster itself.  It is this cluster IP that the primary machine has been reporting that there is an IP confilct with a machine with the mac address of the secondary machine in the cluster.  This cluster ip should only be used by the primary machine in the cluster.  Why do we continually get these IP confilct messages?  There have been a couple of instances where both machines have gone down at the same time.

Thanks so much for you assistance.

Check that the switches the NIX are connected to are set to the same values as the NIC's themselves. If the NIC is set to the speed "Auto" and Duplex "Auto", so should the switch be set to auto. If The NIC is set to 100/Full Duplex, so should the values in the switch be set. If they don't correspond you often get IP conflicts.
