I have 2 - 2008 R2 Virtual servers (VMware) setup for load balancing. Both dual nics..One nic for network and the other for the NLB cluster:
--------- App1 (.188 address) and App2 (.190 address).
When you RDP to 188 (App1), it actually connects to 190 (App2).
If you RDP to 188 (App1) when 188 (App1) is off, it will not connect to anything
If you RDP to 188 (App1) when 190 (App2) is off it will correctly connect to 188 (App1)
