Network Load Balancing - differance between 2019 and 2022

Question

Hi All,

I have a two-node cluster running Windows Server 2019 NLB. When I run an "arp -a" I see ARP tables from the VIP and the NIC that is attached to my LAN. I do not see the NIC that is dedicated to the Cluster. Everything works great.

I am trying to build up the same config on Server 2022. When I run an "arp -a" I see ARP tables from both the Virtual NICs (my LAN and the dedicated Cluster NICs) in the VM and I do not see any entries from the VIP. It doesn't work correctly!

I have compared all the settings in my "live" environment and they are identical (apart from the IP allocations of course). Does anyone have at suggestions? I am sure my issue is ARP related. Why don't I see ARP entries for the VIP in Server 2022?
