Se o IPV6 estiver habilitado, os clientes deverão ter entradas DNS de controlador de domínio válidas nas propriedades do adaptador de rede.
Eu instalei o Windows Server 2016 Datacenter em uma máquina física chamada LOKI . É alocado o IP estático 192.168.1.77 pelo roteador. Também é definido manualmente em TCP/IPv4 na NIC. O gateway está configurado para 192.168.1.1 (o roteador). O servidor DNS primário está definido como 127.0.0.1 . O servidor DNS secundário está em branco. Ao adicionar os Serviços de Domínio do Active Directory e as funções de DNS - optei por criar uma nova floresta: acme.com (estou usando isso como exemplo, mas na verdade é definido como um domínio válido que possuo). O nome de domínio NetBIOS foi definido como ACME .
Eu tentei ingressar em um servidor físico ( BALDER ) no domínio, assim como as VMs estão executando em BALDER . Eu tenho o servidor DNS primário de BALDER em TCP/IPv4 definido como 192.168.1.77 . Tem um IP estático atribuído pelo roteador de 192.168.1.75 . Eu também tentei configurá-lo manualmente em TCP/IPv4 com um gateway de 192.168.1.1 .
Ao ingressar no domínio, estou usando o domínio completo, com o TLD: acme.com .
Ocasionalmente, são solicitadas credenciais. Eu tentei os seguintes usuários:
acme\administrator acme.com\administrator acme\db acme.com\db (onde db é um administrador corporativo). Ao entrar em qualquer credencial, eu recebo:
---------------------------
Computer Name/Domain Changes
---------------------------
The following error occurred attempting to join the domain "acme.com":
The specified domain either does not exist or could not be contacted.
---------------------------
OK
---------------------------
... mas na maioria das vezes eu recebo imediatamente essa mensagem de erro, sem precisar de credenciais:
Note: This information is intended for a network administrator. If you are not your network's administrator, notify the administrator that you received this information, which has been recorded in the file C:\Windows\debug\dcdiag.txt.
The following error occurred when DNS was queried for the service location (SRV) resource record used to locate an Active Directory Domain Controller (AD DC) for domain "acme.com":
The error was: "DNS name does not exist."
(error code 0x0000232B RCODE_NAME_ERROR)
The query was for the SRV record for _ldap._tcp.dc._msdcs.acme.com
Common causes of this error include the following:
- The DNS SRV records required to locate a AD DC for the domain are not registered in DNS. These records are registered with a DNS server automatically when a AD DC is added to a domain. They are updated by the AD DC at set intervals. This computer is configured to use DNS servers with the following IP addresses:
192.168.1.77
- One or more of the following zones do not include delegation to its child zone:
acme.com
com
. (the root zone)
Eu corri dcdiag /fix em LOKI . Todos os testes passam.
Eu corri o seguinte:
nslookup
set type=all
_ldap._tcp.dc._msdcs.acme.com
Em LOKI (o DC) eu recebo:
Server: UnKnown
Address: ::1
_ldap._tcp.dc._msdcs.acme.com SRV service location:
priority = 0
weight = 100
port = 389
svr hostname = LOKI.acme.com
LOKI.acme.com internet address = 192.168.1.77
LOKI.acme.com AAAA IPv6 address = 2a02:c7d:894d:6d00:8dce:ebee:6510:b61c
LOKI.acme.com AAAA IPv6 address = fdc6:f573:1ff9:0:8dce:ebee:6510:b61c
Em BALDER , obtenho:
Server: UnKnown
Address: fdc6:f573:1ff9:0:7250:afff:fe35:beec
*** UnKnown can't find _ldap._tcp.dc._msdcs.acme.com: Non-existent domain
Eu tentei executar isso em LOKI , que é concluído com êxito:
dcdiag /test:registerindns /dnsdomain:acme.com /v
Eu também reiniciei o servidor DNS e reiniciei o NetLogon service.
Eu tentei executar ipconfig /flushdns nos dois LOKI e BALDER .
Eu posso pingar com êxito o DC ( LOKI ) de BALDER , assim como minhas VMs. Não sei se é importante que esteja respondendo com um endereço IPv6 em vez de um IPv4. Endereços IPv6 são definidos dinamicamente pelo DHCP no roteador. De qualquer maneira, está resolvendo com sucesso o FQDN.

Por comentário de Greg, executei este comando:
nltest /dsgetdc:acme.com
A saída parece ser a mesma do DC e de um servidor de junção.
Aqui está a saída de LOKI (o DC):

Apenas para misturar um pouco, executei o PortQueryUI a partir de um servidor diferente - ODIN (uma VM em BALDER ). Eu digitei LOKI no campo IP / FQDN de destino para consultar e deixei o restante das opções como padrões ( Serviço para consulta: Domínios e Relações de Confiança ). / p>
A minha publicação está a exceder o limite de carateres, pelo que carreguei os resultados para o Pastebin.
Eu executei ipconfig /all em alguns servidores de junção - um servidor físico ( BALDER ) e uma VM ( ODIN ). Aqui estão os resultados.

Eu também tentei configurar o sufixo DNS para acme.com , mas isso não ajudou.
O que está me impedindo de ingressar em qualquer computador no domínio?
Defina seu up estático manualmente no servidor para usar a máquina do Controlador de Domínio como o Gateway e defina o DNS manualmente, bem como o controlador de domínio. Em seguida, tente ingressar no domínio.
Defina-os de volta para dinâmicos depois de ingressar no domínio.
