Hi all,
I have a windows 2012r2 failover cluster and recently I noticed that the cluster name is offline due to a failure of its IP Address:
Health check for IP interface 'Cluster IP Address' (address '10.16.18.70') failed (status is '55'). Run the Validate a Configuration wizard to ensure that the network adapter is functioning properly.
I've run the validation wizard (only for the network part coz the cluster is in production since some months) and everything is ok. If I try to bring online the IP addrees I receive a failure.
