I have three nodes, all brand new fresh R2 installs with nothing but Hyper-V role installed and failover clustering feature enabled. I am trying to run the failover cluster validation tests and everything passes but it fails at the Firewall Configuration section with a weird error (see below). The firewall hasn't been touched on any of the machines except by installers to enable iSCSI and iSCSI MPIO. If anyone can help I would great appreciate it...I haven't a clue in the world what this means. Thanks!
An error occurred while executing the test.
There was an error verifying the firewall configuration.
An item with the same key has already been added.
