Hosts in a Network Load Balancing (NLB) cluster are configured to load balance network traffic. Host configuration is set by using NLB Manager, and if it is not configured properly, the NLB cluster may not function correctly.
Confirm NLB configuration settings
If Network Load Balancing (NLB) is unable to process its configuration settings, you should confirm that the settings are correctly configured, and then, if changes are made, restart the NLB cluster.
Confirm the NLB configuration
To confirm the NLB configuration:
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.
If NLB Manager does not already list the cluster, connect to the cluster.
Right-click the cluster, and then click Cluster Properties.
As required, reconfigure the properties.
When you are using nlb.exe, 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.exe 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.
Restart the NLB cluster
To restart the NLB cluster:
Open an elevated Command Prompt window. Click Start, point to All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator.
Type nlb.exe reload, which reloads the NLB driver's current parameters from the registry.
Type nlb.exe start, which starts cluster operations on the specified hosts.
You can also reload the configuration and restart the cluster node using the links below:
