Usually this messages occurs after you change the cluster SERVICE ACCOUNT password.
Have you done this recently? If so, you must stop and restart the Cluster service on both nodes after you change either the Cluster service account or the Cluster service password. More info on this: http://support.microsoft.com/kb/317232

Also, check to make sure the specified network is available and functioning correctly. If you are running a firewall, disable it for now and see if you can connect.
