I am wondering if you are mixing up netbios and dns here ?
netbios is what the earlier workgroups and NT4-style domains used to
find each other, or in other words 'network browsing'
If you are not using SMB1 (and you really shouldn't be) you will not be
using 'network browsing'.

Why do you think you need 'netbios aliases' ?
