    Q. What is Network Load Balancing?

    A. Network Load Balancing is a clustering technology offered by Microsoft as part of all Windows 2000 Server and Windows Server 2003 family operating systems. NLB uses a distributed algorithm to load balance network traffic across a number of hosts, helping to enhance the scalability and availability of mission critical, IP-based services, such as Web, Virtual Private Networking, Streaming Media, Terminal Services, Proxy, etc. It also provides high availability by detecting host failures and automatically redistributing traffic to operational hosts.

    Accepted Solution

    NLB is used to share load between servers.
    When you look at an NLB from an user point is is seen as a single point of entry but in fact it is an array
    of different servers that handle requests.

    Here is some reading on NLB clusters.

    Good luck,
