I have a a SQL Server 2005 Failover Cluster with two nodes. Node A & Node B. SQL is running on Node B. About 2 weeks ago, we failed over to Node A. Then after the problem was corrected, we failed back to Node B. Everything seems good, and I see no errors in the system or Application Event Logs on the boxes. They are both running Server 2008 R2 Enterprise and SQL 2005 Enterprise.
I have two web servers, both running Windows 2008 R2 Enterprise. Both boxes are on the same subnet. Since failover that occurred 2 weeks ago, Server 1 works normally, but server 2 is unable to connect to sql on the cluster. Nothing has changed on either web server. Server 2 cannot ping the cluster name or IP address; however, it does resolve the name to the correct IP Address. Server 2 can ping both nodes individually (on the same subnet as the cluster IP). I'm completely at a loss as to why this is happening. Any thoughts / suggestions would be wildly helpful.
