Hi, We have microsoft NLB to.
I must say this was a little bit tricky. First we used unicast NLB and this flooded all ports on the same vlan. But then we configured igmpsnooping and set the servers to use multicast with IGMP. The flood stopped and the servers work fine as before. I advise you to try the same.
