It's on Hyper-V, I believe. I read that you need two NICs for unicast, so I've got the server admins to add a second NIC which I am now going to configure.
I was stopping IIS and expecting it to failover, but that appears to be out of scope for NLB, as far as I can tell from this discourse. I will try disabling it in NLB Manager, as rebooting brings it back too quickly to tell if it's failed over or not, and I don't have access to Hyper-V to shut it down. I am assuming that although it can't do intelligent failover, it does do intelligent load balancing - i.e. it will route connections to the server with the least load?
