I've been having issues with a few new intel board based PC's i've deployed. I receive reports of network slowness and run wireshark and notice millions of packets for ICMPv6 Multicast Listener Report. I attempted to unbind IPv6 from the adapter as well as run the MS fixit tool to completely disable ipv6 on these machines to no avail, our GPO is also set to disable IPV6 and its functionalities across the whole network


I tried removing the intel management software to see if this may be causing it, but that didn't seem to help. I suspect this is some function of the Intel NICs installed in these PCs, but I'm at a loss as to how to manage or disable it! I've contacted intel and they are not willing to accept any blame that its their nic card at fault
