samba mint linuxでうまく表示された設定

sambaはnameserverの設定が悪いとうまく表示されない

dhcpの設定

default-lease-time 86400;
max-lease-time 172800;
option subnet-mask 255.255.255.0;
option broadcast-address 192.168.1.255;
option routers 192.168.1.1;
option domain-name-servers 192.168.1.2;

smb.confの設定

[global]
workgroup = LIS
server string = Samba Server %v
netbios name = ubuntu
security = user
map to guest = bad user
dns proxy = no

os level = 64

os level = 64 これがsambaを解決するserverですよの設定のようだ
