Cluster network '%1' is down because the network interfaces connected to it are not operational. Cluster network '%1' is configured such that cluster communication is not allowed; however, if this failure is unexpected, run the Validate a Configuration wizard to check your network configuration. If the condition persists, check for hardware or software errors related to the network adapter. Also check for failures in any other network components to which the node is connected such as hubs, switches, or bridges.
