Problema do Active Directory / DNS

3

Estou tendo alguns problemas com nossa resolução de nome de domínio local por algum motivo. Uma breve descrição da minha rede inteira é: Temos dois escritórios. Cada escritório tem seu próprio DC e seu próprio firewall, mas ambos os escritórios são replicados entre si. Agora, uma das redes do escritório está funcionando bem, a que estou tendo problemas é a que estou usando atualmente.

Como exemplo, posso acessar \\ server1 \ myshare, mas não consigo acessar \\ mydomain.net \ myshare na minha rede atual. Na outra rede, tudo está funcionando bem. Agora, em intervalos aleatórios quando estou no RDP no servidor1, consigo acessar o domínio, mas outras vezes não consigo. Acredito que localizei o culpado, mas ainda não sei como começar a corrigir esse problema. Aqui está a saída do dcdiag:

   Testing server: BGS-HQ\BGS-HQ-VRDSVR01
      Skipping all tests, because server BGS-HQ-VRDSVR01 is not responding to

Agora ... a parte divertida disso é que eu corri o seguinte:

C:\Users\Administrator>nslookup 6282bfca-ade1-41c8-84dc-516ce19b49be._msdcs.bill
sgs.net
Server:  bgs-hq-vrdsvr01.billsgs.net
Address:  192.168.40.13

Name:    bgs-hq-vrdsvr01.billsgs.net
Address:  192.168.40.13
Aliases:  6282bfca-ade1-41c8-84dc-516ce19b49be._msdcs.billsgs.net

Qualquer sugestão sobre isso seria muito apreciada. Eu sou um programador, não um administrador de rede, então eu certamente não conheço muitas técnicas de depuração com isso, e especialmente com o Windows Server.

Além disso, como nota lateral, desativamos o servidor de replicação por enquanto, por algum motivo, ele está literalmente usando todos os 12 GB de RAM no servidor. Eu não tenho certeza se isso está relacionado, mas a partir de agora está em segundo plano.

EDIT: Peço desculpas, estamos executando o Windows Server 2008 R2 e abaixo é um ipconfig / all do servidor.

Para ver se isso é relacionado ao firewall baseado em host, desative temporariamente o domínio e os perfis público e privado. Você tem várias interfaces, como no Windows Server 2008, o perfil mais restritivo está em vigor. Execute isso a partir do prompt de comando elevado

  • netsh advfirewall define o estado do publicprofile desativado
  • netsh advfirewall define estado do perfil de privacidade desativado
  • netsh advfirewall define o estado do perfil de domínio desativado

O uso da memória pode ser enganoso. Muitas vezes é usado, mas liberado quando necessário. Consulte o log de eventos operacionais do detector de exaustão de recursos (abra eventvwr e vá para aplicativos e serviços / microsoft / windows / resource exaustment detector / operating) para determinar se a falta de memória está acabando.

Use o Process Explorer para ver o uso da memória e ver o que está disponível. Se a aparência estiver baixa, verifique com o RAMMap da Syinternals para ter uma idéia do uso. Veja o RAMmap explicado no link porque tive casos em que metarquivo estava "consumindo" isso. Mas era um comportamento esperado.

O erro 81 no DCDiag indica que o servidor LDAP estava inacessível. Você tem algum produto de terceiros no próprio DC fornecendo o comportamento incluído do Antivirus + Firewall? Se você puder acessar o LDAP enquanto estiver no DC, mas não remoto, e se tiver certeza de que nenhum firewall baseado em host está em uso, eu verificaria se algum dispositivo de rede intermediário está filtrando / descartando pacotes.

Se você tiver uma rede pública em qualquer um dos adaptadores, certifique-se de que o servidor DNS principal seja o "ip público de si mesmo" que resolveu o problema para mim.
