Hello.
I have installed two Exchange 2010 CAS-HUB Server in a cas array under Windows 2012. I have deployed NLB in both servers. Few days ago, only the node where I'm logged in has shown on NLB Administration Console. I have tried to add the other node, but I received a messagge about this node is already part of this cluster.
I have validated this parameter on registry HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\Tcpip\Parameters\Adapters in order to remove all adapters without use, but after remove it, it come back.
Thanks and regards
