Can't access cluster via SQL Server Mng Studio unless node has ownership

Hi:

We have Windows and SQL 2008 R2 in a 2 node cluster. Failover and failback work like a dream. All the 'lights' are green. But we can only access the cluster when we're on the node that has ownership. I've deleted all DNS entries and successfully recreated them via ipconfig /registerDns from each node, shutting down, restarting the actual cluster and taking the application and service offline then back on line. All DNS records got recreated perfectly. Cluster error log doesn't show anything when we can't connect either. We can also ping all IPs, Hostnames and Clustername.
