Estou pesquisando um problema de login com falha que está acionando nosso software de monitoramento.
Pesquisando o problema, a única outra informação que eu pude descobrir que era exatamente o que eu estava vendo, estava aqui: Evento 4625 Falha na auditoria NULL SID falha em logons de rede
Tentando rastrear isso, usei o Process Monitor e configurei 2 filtros:
Process IS lsass.exe
Resultado NÃO É SUCESSO.
Em seguida, combinei os resultados com as tentativas de Auditoria com falha e parece corresponder a essas duas linhas no monitor de processo, conforme elas foram exibidas a cada vez no momento exato da Falha de Auditoria:
1:05:47.4932903 PM lsass.exe 896 RegOpenKey HKLM\Software\Policies\Microsoft\SystemCertificates\Root\ProtectedRoots NAME NOT FOUND Desired Access: Read
1:05:47.4941867 PM lsass.exe 896 RegQueryValue HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\ForceAutoLockOnLogon NAME NOT FOUND Length: 144
Não tenho certeza se estou procurando o local certo para rastreá-lo ou o que fazer agora. Alguma sugestão?
Eu sou novo no serverfault, então não pude comentar ou responder a pergunta no link acima, mas ficaria curioso se ele / ela visse os mesmos resultados com o monitor de processo.
