urgent___cluster node constantly removed from active cluster membership

-

hi all,

one client  just set windows 2012 r2 clustering , sql 2012 on.  two site , b.  at site a(producton site), 4 nodes .  two nodes have 2 nics (one private replication; client , cluster communication); 2 nodes 1 public nic.  cluster node removed active cluster membership event 1135.  private network down error;  same as http://blogs.technet.com/b/askcore/archive/2012/02/08/having-a-problem-with-nodes-being-removed-from-active-failover-cluster-membership.aspx

i not understand how these 4 nodes communicate each other since (two nodes have 1 private , 1 public ips; other 2 have 1 public ip). can let me know how heartbeats work among these 4 nodes? not think driver issue since 2 nodes physical , 2 nodes virtual.

how should make these errors go away?  do need adjust these values according to http://www.sqlhammer.com/blog/set-windows-failover-cluster-timeout-thresholds/?

btw, can let me know how heartbeats work among th

thank much!
