Accepted Solutions. Thanks, Wally. Hi Wally, Thanks for the reply. Best regards,. I came across following information Multicast mode With the Windows NLB cluster configured in multicast mode, a multicast MAC address is added to the cluster adapter of each server in the cluster.

There are disadvantages in multicast method The multicast method has the following disadvantages: Upstream routers might require a static Address Resolution Protocol ARP entry. Without IGMP, switches might require additional configuration to tell the switch which ports to use for the multicast traffic. In these situations, you must upgrade or replace the router.

With the cluster now configured and running, the next step is to add additional nodes to the cluster. Before adding a new host to a cluster it is first necessary to install the Network Load Balancing feature on the new server as outlined previously in this chapter.

If no cluster is currently listed, right click on Network Load Balancing Manager entry and select Connect to Existing. In the connection dialog enter the name or IP address of a node in the cluster or the IP address of the cluster itself and click on Connect.

Per-program mode: In per-program mode, Remote Desktop IP Virtualization facilitates shared-session IP, but only uses it for specified applications instead of the whole session. The remaining applications in the session will continue using the overall server IP.
