Since you didn't want to follow my advice above, I will post VMware's official statement on Unicast NLB. YOu will note the first bullet point precludes you from running it on two nodes.
VMware recommends configuring the cluster to use NLB multicast mode even though NLB unicast mode should function correctly if you complete these steps. This recommendation is based on the possibility that the settings described in these steps might affect vMotion operations on virtual machines. Also, unicast mode forces the physical switches on the LAN to broadcast all NLB cluster traffic to every machine on the LAN. For more information on the differences between multicast and unicast, see Microsoft Network Load Balancing Multicast and Unicast operation modes (1006580). If you plan to use NLB unicast mode, note that:
- All members of the NLB cluster must be running on the same ESXi/ESX host.
- All members of the NLB cluster must be connected to the single portgroup on the virtual switch.
- vMotion for unicast NLB virtual machines is not supported (unless you want to migrate all NLB members to a different ESXi/ESX host).
