Applies To: Windows Server 2008, Windows Server 2008 R2, Windows Server 2012

Network Load Balancing (NLB) is an optional component in the Windows Server® 2008 operating system that load balances network traffic (sent to a cluster virtual IP address) among multiple servers in an NLB cluster. This guide provides information on deploying NLB.


The NLB functionality in Windows Server 2012 is generally the same as in Windows Server 2008 R2. However, some task details are changed in Windows Server 2012. For information on new ways to do tasks, see Common Management Tasks and Navigation.
