Enviado em 16/07/2015 - 13:13h

Olá, bom dia, estou configurando uma rede com máquinas linux e windows pela 1a vez. Tenho um servidor Samba rodando em um ubuntuserver. Estou com problemas para acessar o servidor samba a partir das maquinas windows 7

Quando altero as configurações de dominio em "Meu Computador", a seguinte mensagem é exibida:

"Não foi possível contatar um Controlador de Domínio do Active Directory (AD DC) para o dominio "orcs".

Verifique se o nome de dominio foi digitado corretamente.


Segue abaixo meu arquivo smb.conf

#

# Sample configuration file for the Samba suite for Debian GNU/Linux.

#

#

# This is the main Samba configuration file. You should read the

# smb.conf(5) manual page in order to understand the options listed

# here. Samba has a huge number of configurable options most of which 

# are not shown in this example

#

# Some options that are often worth tuning have been included as

# commented-out examples in this file.

#  - When such options are commented with ";", the proposed setting

#    differs from the default Samba behaviour

#  - When commented with "#", the proposed setting is the default

#    behaviour of Samba but the option is considered important

#    enough to be mentioned here

#

# NOTE: Whenever you modify this file you should run the command

# "testparm" to check that you have not made any basic syntactic 

# errors.

#;   wins server = 10.0.1.23



# This will prevent nmbd to search for NetBIOS names through DNS.

   dns proxy = no



#### Networking ####

# This can be either the interface name or an IP address/netmask;

# interface names are normally preferred

;   interfaces = 127.0.0.0/8 eth0



# Only bind to the named interfaces and/or networks; you must use the

#### Debugging/Accounting ####

# that connects

# Running as "active directory domain controller" will require first

# running "samba-tool domain provision" to wipe databases and create a

# new domain.

# password database type you are using.

# password with the SMB password when the encrypted SMB password in the

# to anonymous connections

Alterei as configurações de rede da maquina windows, colocando no dns o ip da maquina linux e adicionando na aba "wins" o ip da maquina linux.
Alterei propriedades das DWORDS DomainCompatibilityMode para 1, DNSNameResolutionRequired para 0, RequiredSignOrSeal para 1 e RequireStrongKey para 1 usando o Editor de Registros.

Após estas alterações o erro continua.

Alguém que já tenha passado por este problema tem alguma sugestão?

Obrigado,

Então, resolvi mudar algumas coisas: instalei o Debian 8.01 e instalei o samba 4.1.17.

Vou compartilhar a pasta 'security' com máquinas windows. Criei um grupo security no linux, criei um usuario e o associei a este grupo. Este mesmo usuário foi criado no samba. Então quando tento mapear a unidade de rede numa maquina cliente (windows 7), aparece o nome do servidor e da pasta, e então aparece a tela de login... digito login e senha do usuário que foi criado...o windows demora uns minutos e então exibe uma mensagem: "a unidade de rede especificada não pôde ser criada porque ocorreu o seguinte erro: o nome da rede especificado não está mais disponível "
