To install Network Load Balancing if it was previously uninstalled

  1. Open Network Connections.

    Important

    • To avoid networking problems, follow these steps in the exact order shown.

  2. Right-click the Local Area Connection on which Network Load Balancing is to be installed, and then click Properties.

  3. Click Install.

  4. In the Select Network Component Type dialog box, click Service, and then click Add.

  5. In the Select Network Service dialog box, click Network Load Balancing, and then click OK.

    Important

    • Do not select the check box for Network Load Balancing at this point. When you configure the cluster using Network Load Balancing Manager (in the next step), Network Load Balancing Manager will automatically enable this service.

  6. Use Network Load Balancing Manager to configure the cluster. For more information, see "Enable Network Load Balancing" in Related Topics.

Notes

  • To perform this procedure, you must be a member of the Administrators group on the local computer, or you must have been delegated the appropriate authority. If the computer is joined to a domain, members of the Domain Admins group might be able to perform this procedure. As a security best practice, consider using Run as to perform this procedure.

  • To open Network Connections, click Start, click Control Panel, and then double-click Network Connections.

  • If Network Load Balancing clients are accessing a cluster through a router, be sure that the router meets the following requirements:

    • Accepts a dynamic Address Resolution Protocol (ARP) reply mapping the unicast IP address to its unicast media access control (MAC) address

    • In multicast mode, accepts an ARP reply that has a MAC address in the payload of the ARP structure. If your router does not meet these requirements, you can also create a static ARP entry in the router. Cisco routers require a static ARP entry because they do not support the resolution of unicast IP addresses to multicast MAC addresses.

  • If only one Local Area Connection icon is displayed in Network Connections, you have only one network adapter installed on your computer. Additional network adapters are represented by additional Local Area Connection icons.

  • When installing Network Load Balancing, you might expect to find a setup application (such as Setup.exe). There is no such application. The Network Load Balancing driver is installed as a standard Windows networking driver.

Information about functional differences

  • Your server might function differently based on the version and edition of the operating system that is installed, your account permissions, and your menu settings. For more information, see Viewing Help on the Web.
