dc2

mv /etc/samba/smb.conf /etc/samba/smb.conf.dist

    --username=EXAMPLE\\administrator \
    --dns-backend=SAMBA_INTERNAL \
    --option="interfaces = lo eth0" \

fix the netbios name

vi /etc/samba/smb.conf

[global]
    bind interfaces only = yes
    interfaces = lo eth0
    netbios name = DC2
    realm = EXAMPLE.LOCAL
    server role = active directory domain controller
    workgroup = EXAMPLE

[sysvol]
    path = /var/lib/samba/sysvol
    read only = No

[netlogon]
    path = /var/lib/samba/sysvol/example.net/scripts
    read only = No
