Initially I configured 2 machines each with one synthetic network card. I followed your guide on how to create an nlb cluster and configured those adapters accordingly.
Once nlb was setup I lost all network connectivity to those machines. Removing nlb would bring back network connectivity. Based on a previous post I decided to remove the synthetic network adapter and install the legacy network adapter. This time nlb worked. I then proceeded to do the same thing on my windows 64bit virtual machines. At this point I realized there are no windows 64bit drivers for the legacy network adapter. Thx Farah.

In this article I will load balance 2 servers and take you through the process step-by-step. Load Balancing takes 2 or more servers and lets them share one IP address so both servers can serve client requests. At the end of this article you should be able to configure NLB. In this example both servers only have one network card. If you have multiple network cards you will still be able to load balance the 2 servers. Open "Network Connections" from the control panel.
Check off the "Network Load Balancing" option and press "Properties".

None You want to ensure even load balancing among cluster hosts Client traffic is stateless for example, HTTP traffic.
Single You want to ensure that requests from a specific client IP address are sent to the same cluster host.
