Boa tarde.
Temos um servidor rodando com o Active Directory do Windows Server 2016, e no começo desta semana, alguns sites pararam de abrir, mostrando a mensagem de erro de DNS "DNS_PROBE_FINISHED_NXDOMAIN", se no terminal eu deixo para buscar o DNS automaticamente, a página abre, porém se volto ao DNS do servidor, algumas páginas não abrem. Alguém saberia me dizer se é alguma configuração errada no DNS, vista que ele funcionava normalmente?
