Check that the virtual IP address is valid

The virtual IP address must be in a valid IPv4 or IPv6 format.

To check that the virtual 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 cluster, and then click Cluster Properties.

  • 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.
