Traffic in Microsoft Network Load Balance
Posted on 2010-11-29
I just implemented a NLB for Terminal Services in 3 Windows 2003 Standard Servers. Connection distribution looks working fine, but if I have one active connection and I take a look at the network card's traffic in any other computer in the network, I can see the traffic from the client to the NLB cluster. So, looks like my network switch is doing a broadcast for traffic destinated do the cluster's IP address.
The NLB is configured with only one network card in each server and running in multicast mode.
Why is this happening and how can I resolve this?
