WSFC Windows2019 create Computer Account, but not register DNS name.

Question

When building WSFC with two Windows2019 nodes, the Cluster is completed, but the name resolution of the Cluster IP fails.
("Cluster IP" refers to the IP displayed inside the Cluster Core Resource.)

When I checked the resource status in AD, the Computer Account for ClusterIP was created, but the DNS name was not registered.

In previous versions of Windows this was a registered recognition, has the behavior changed?

Also, how can I fix this issue?

Thank you.

Answer 1

Hello there,

This behavior is by design. It occurs because NetBIOS no longer binds to IP address resources in Windows Server 2016 or later versions of the Windows Server-based Cluster service.

To work around this behavior, use the Cluster Management console to determine the name of the IP address resource that must be changed.

NetBIOS and WINS don't bind to cluster IP address resources https://learn.microsoft.com/en-us/troubleshoot/windows-server/high-availability/netbios-wins-dont-bind-cluster-ip-address-resources
