The latest versions of Windows have SMBv1 turned off by default, but can 
be turned on again, but this is not recommended. To use netbios, you 
need SMBv1, Samba is working towards removing SMBv1 and, like Windows, 
has turned it off by default, but it can be turned on again, this is not 

Eventually, SMBv1 will be removed from Samba, whether this is before or 
after Windows removes it, is up to Windows, but it will be removed by both.

If you are still using netbios, can I suggest you make plans to stop 
using it, before you are forced to.
