Use the following procedure to configure Network Load Balancing (NLB) cluster parameters. You perform this procedure on only a single host. All hosts will automatically inherit the cluster configuration from the initial host. The parameters that you set in the Properties dialog box are recorded in the registry of each host.

You can also perform the task described in this procedure by using Windows PowerShell. For more information about using Windows PowerShell for NLB clusters, see http://go.microsoft.com/fwlink/?LinkId=140180.

When you are using Network Load Balancing (NLB) Manager, you must be a member of the Administrators group on the host that you are configuring, or you must have been delegated the appropriate authority. If you are configuring a cluster or host by running NLB Manager from a computer that is not part of the cluster, you do not have to be a member of the Administrators group on that computer.

To ensure that Network Load Balancing Manager is displaying the most recent host information, right-click the cluster and click Refresh. This step is necessary because the host properties that Network Load Balancing Manager displays are a copy of the host properties that were configured the last time Network Load Balancing Manager connected to that host. When you click Refresh, Network Load Balancing Manager reconnects to the cluster and displays updated information.

To configure Network Load Balancing Cluster parameters

  1. To open NLB Manager, click Start, click Administrative Tools, and then click Network Load Balancing Manager. You can also open NLB Manager by typing Nlbmgr at a command prompt.

  2. If NLB Manager does not list the cluster, connect to the cluster.

  3. Right-click the cluster and choose Cluster Properties.

  4. On the Cluster Parameters tab, specify values for IP address, Subnet mask, Full Internet name, and Cluster Operation Mode.

Note

Changes to NLB parameters are applied when you click OK in the Properties dialog box. Clicking OK stops NLB (if it is running), reloads the parameters, and then restarts cluster operations.
