Network Load Balancing one node stuck on Converging

Windows Server 2012 R2.

I have three nodes in a network load balancing cluster.  As long as I don't add any port rules, all three nodes converge no problem.  But once I add a rule, nodes 1 and 2 converge but 3 gets stuck on converging and when I click on node three under the Network Load Balancing Manager, the status is Pending for the rule.  

Rules I needed added are:
21 for FTP
80 for IIS
443 for IIS

I right click on the Gateway itself and go to Cluster Properties to add port rules.  That's supposed to allow all three nodes to inherit the same rules.

Thank you all in advanced for your help.

How many NICs do the servers in the NLB each have?

Can you run the command below on each node and post:

WLBS display

All three nodes have two NICS.  Both NICS have static IP's that are in the same VLAN.

All three servers in the GATEWAY NLB.

Are these physical or virtual servers?

Also, why do the servers have 2 NICs on the same subnet.  This can cause packet send/receive issues on the servers.

Have you tried disabling the non-WLBS NIC to see if convergence occurs?
