Rule Knowledgebase

Summary

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.

Causes
This rule does not contain any causes.
Resolutions

Ensure that all NLB hosts have unique host priorities

If a Network Load Balancing (NLB) host has a host priority that is identical to the host priority on another host, or the host priority is not valid, the cluster will not converge until the problem is corrected. The host priority must be a number from 1 through 32, and this value must be unique for all hosts in the cluster.

To ensure that all NLB hosts have a unique host priority:

  • 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.

  • Click the Port Rules tab. In the Defined port rules list, review each host to make sure that each host has a unique host identifier.

  • If there are host identifiers that are not unique, right-click the host for which you want to reconfigure the host identifier, and then click Host Properties.

  • Click the Host Parameters tab, and in Priority (unique host identifier), specify a value between 1 and 32.
