Summary

The dedicated IP addresses in Network Load Balancing (NLB) must be properly configured and be able to contact individual NLB cluster hosts. If the dedicated IP address is not configured correctly, you cannot use it to manage the host or for other non-cluster-related communication.

Causes
This rule does not contain any causes.
Resolutions

Limit the number of dedicated IP addresses on network adapter

If the number of dedicated IP addresses added to a network adapter has exceeded the maximum number allowed by the adapter, you will need to remove one or more IP addresses. The extra dedicated IP addresses will be ignored by the Network Load Balancing (NLB) cluster.

To limit the number of dedicated IP addresses:

  • 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 host that you want to configure, and then click Host Properties.

  • Click the Host Parameters tab.

  • In IP address, remove one or more addresses until the maximum number allowed by the network adapter is reached.
