To restart handling Network Load Balancing cluster traffic

Using the Windows interface

Using a command line

Using the Windows interface

  1. Open Network Load Balancing Manager.

  2. If Network Load Balancing Manager does not already list the cluster, connect to the cluster.

  3. If you want to start cluster operations on all cluster hosts, right-click the cluster, and then point to Control Hosts.

    Or, if you want to start the cluster service on only a particular host, right-click the host, and then point to Control Host.

  4. Click Start

Important

  • To start Network Load Balancing Manager, open a Command prompt. From the command window, type NLBMgr, and then press ENTER.

Notes

  • When using Network Load Balancing 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. As a security best practice, consider using Run as to perform this procedure. If you are configuring a cluster or host by running Network Load Balancing Manager from a computer that is not part of the cluster, you do not need to be a member of the Administrators group on that computer. For more information, see Default local groups, Default groups, and Using Run as.

  • To start Network Load Balancing Manager, open a Command prompt. From the command window, type NLBMgr, and then press ENTER.

  • This command can be used after a previous stop or suspend command. It restarts cluster operations. It does not reenable the use of cluster-control commands, including remote control commands, which have been disabled by a previous suspend command. For information on how to reenable cluster-control commands, see "To resume Network Load Balancing" in Related Topics.

  • You should not use the start command to form a new cluster. For more information, see "Enable Network Load Balancing".

Using a command line

  1. Open Command Prompt.

  2. Type:

    nlb.exe start

    Or, if you want to start cluster operations on all cluster hosts, type:

    nlb.exe startcluster IP address | cluster name

Notes

  • To run nlb.exe from a remote computer, you must enable remote control on the host that is running Network Load Balancing. The Network Load Balancing remote control option presents many security risks, including the possibility of data tampering, denial of service and information disclosure. Only use remote control on a secure computer within your firewall. Because of the many security risks remote control presents, it is recommended that you do not enable the remote control feature. Instead, use other remote management tools such as Network Load Balancing Manager or Windows Management Instrumentation (WMI).

  • To open a command prompt, click Start, point to All programs, point to Accessories, and then click Command prompt.

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.
