3.3. Set Interfaces to IPv4 Preferred

Configure all the Windows Server nodes in your cluster to use IPv4 addresses only. You can either disable IPv6, see How to disable IP version 6 or its specific components in Windows or set the preference to IPv4.

Ensure that the host FQDN resolves to an IPv4 address as follows:

  1. Open a command prompt and verify that IPv4 is set to preferred:

    ipconfig /all
    
    Connection-specific DNS Suffix . . : 
    Description . . . . . . . . . . .  : Intel(R) PRO/1000 MT Network
    Connection Physical Address. . . . : XX-XX-XX-XX-XX
    DHCP Enabled. . . .   . . . . . .  : No 
    Autoconfiguration Enabled .  . . . : Yes 
    IPv4 Address. . . . . . . . .  . . : 10.0.0.2(Preferred) 
    Subnet Mask . . . . . . . . . . .  : 255.255.255.0 
    Default Gateway . . . . . . . . .  : 10.0.0.100 
    DNS Servers . . . . . . . . . . .  : 10.10.0.101 
    NetBIOS over Tcpip. . . . . . . .  : Enabled
  2. Flush the DNS cache:

    ipconfig /flushdns
  3. Verify that the hostname of the system resolves to the correct IP address:

    ping -a 10.0.0.2
