Hello.
I'm having an issue with two VMs 2008 R2 running onto my 2012 R2 hyper-v cluster (two nodes). When I finished the configuration of the NLB between my VMs everything starts working as expected, but after a few seconds the NLB I've configured in my VMs stops working.
I already tried unicast, multicast and IGMP multicast modes in my NLB, changed the host priority, uninstalled the latest updates from the VMs and the hosts and the problem persist. I also tried to install the KB4457133, but I get the error "it doesn't apply for my operating system".
The only thing I didn't try yet is build again my 2012 R2 hyper-v cluster from scratch without applying any Windows updates.
I hope to find here a light at the end of the tunnel, someone have some tip?
Thanks a lot!
Mauro.
