Samba no Ubuntu 14.04 funciona normal?

Pessoal estou com uma maquina com o Ubuntu 14.04 LTS instalado e o samba sendo executado, porém nenhuma maquina com windows 7 prof. consegue enchegar os compartilhamentos.

teste@srv-ubuntu2:~$ smbd -V
Version 4.1.6-Ubuntu

aparece a mensagem padrão;
"Windows cannot access \\192.168.0.17"

segue o smb.conf que estou usando no samba
