When LifeKeeper activates a VIP resource (with the same IP address as the NLB IP address and the Windows OS automatically registers the VIP address/computer name pair with the DNS server, causing LifeKeeper GUI to resolve to the VIP address when resolving the name from the computer name to the IP address. To prevent this, disable dynamic DNS updates for the NICs that activate LifeKeeper VIP resources.

  1. Start PowerShell for administrators.
  1. Run the ipconfig command and check the network adapter names of the primary and secondary NICs from the configured IP addresses. Perform the following steps for both the primary and secondary NICs.
  1. Execute the following command using the network adapter name identified in the previous step.
    PS > Get-DnsClient -InterfaceAlias <network_adapter_name> 
  1. Check the RegisterThisConnectionsAddress column in the results from the previous step. If it is True, run the following command to disable RegisterThisConnectionsAddress.
    PS > Set-DnsClient -InterfaceAlias <network_adapter_name> -RegisterThisConnectionsAddress $false
