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:
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
Flush the DNS cache:
ipconfig /flushdns
Verify that the hostname of the system resolves to the correct IP address:
