O Win 10 Network Discovery não está mais atendendo aos meus servidores Ubuntu. Foi trabalhando até alguns meses atrás. Todos os meus sistemas Win10 vêem um ao outro. Meus servidores Ubuntu podem ver um ao outro. Mas não há Ubuntu < - > Win10 acontecendo.
A coisa verdadeiramente enlouquecedora é que eu posso ver o pedido de sessão NBT / respostas no lado do servidor.
Ainda posso acessar os compartilhamentos manualmente, eles simplesmente não aparecem em "Rede".
