Hi, to add to what has already been said, some applications still require netbios to work. It’s mostly a legacy protocol been phazed out, but still enabled by default in the wins tab of the network card properties.
When you type a command like ‘net use’ it will use netbios to find the server name.
A newer protocol called llmnr is trying to replace it.
Dns can go out to the internet but netbios is on the local lan segment.
