Here is a quick guide how to set up two Web Servers that will be serving out the same web page for redundancy and load balancing purposes. When we go to www.mywebsite.com address, the name will resolve to the Load Balancing IP/Cluster IP (192.168.10.30) and then the Load Balancing manager will either take us directly to WebServer-1 (192.168.10.10) or WebServer-2 (192.168.10.20) depending on the load and server availability.
I have set this up where each machine is using only one network adapter, this will still work perfectly fine but you will get a pop up message every time you open the Load Balancing Manager complaining about the machines may not be able to communicate with each other. The problem is that in Unicast mode the machines get an identical MAC address and the machines may not be able to communicate with each other.
As per Microsoft’s best practice you should set this up the same way but add an additional network card and make that your primary IP for this machine. The IP’s and network adapters involved in load balancing should only be used for load balancing.
Load Balancing IP (192.168.10.30)
WebServer-1 (192.168.10.10) WebServer-2 (192.168.10.20)
6. Load Balancing IP (Cluster IP)
2. Open up the “Network Load Balancer Manager” on WebServer-1. You should already have it open from configuring WebServer-1.
3. Add the second host to the cluster which is WebServer-2.mylab.local
