Rule Knowledgebase

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

Resolutions

Ensure that the dedicated IP address is in a valid format

If the dedicated IP address is not valid, the Network Load Balancing (NLB) cluster will converge and operate normally without the IP address. However, if the IP address is required for remote cluster management, make sure that the IP address is specified in a valid IPv4 or IPv6 address format.

To ensure that the dedicated IP address is in a valid IPv4 or IPv6 format:

  • 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, and, in IP address, verify that the IPv4 or IPv6 address is correctly formatted. IPv4 addresses use the standard Internet dotted notation (for example, w.x.y.z). IPv6 addresses use 16-byte addresses, typically expressed in colon-hexadecimal notation. Colon-hexadecimal notation uses eight 4-digit hexadecimal numbers, with colons separating the 16-bit blocks (the 4-digit numbers). To manage addresses more easily, IPv6 suppresses leading zeros and compresses a single contiguous all-zero 16-bit block, represent the contiguous block with two colons (::). This is known as double-colon compression. An example of an IPv6 address with leading zeros suppressed is: FEC0:0:0:0:2AA:FF:FE3F:2A1C.
