Hi
This blog post is about a feature that is really less used today, but some of you might still need it, WINS.
In case you try to make a WINS cluster you must know that Microsoft by default, from 2016, now block NetBIOS on the cluster IP. It would make it look like the port 137 is blocked.
To find the correct IP, open up MMC, Cluster, Roles, WINS and find the IP.
After we have the IP, we enable the NetBIOS that way with PowerShell;
Get-ClusterResource “IP-address” | Set-ClusterParameter EnableNetBIOS 1
A small tip, but still handy if you happen to need it.
