Erro ingressar Win7 no dominio Server 2008.

Estou encontrando muita dificuldade ao tentar colocar uma maquina Win7 64Bit no domínio com Server 2008 64Bit, aparece o seguinte erro.

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.omega.local

Já tentei algumas opções sem sucesso, fiz pesquisas e percebi que está faltando uma zona ou parâmetro aquelas criadas pelo AD no DNS como podem ver na imagem abaixo. Mas não sei como criar.



OBS: As máquinas pinga umas as outras, o nslookup funciono no cliente e servidor.
