Novo servidor 2012 R2 Essentials gerando falha de auditoria Evento 4625 Tentativas de logon SID nulo

2

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.

Aqui está um evento do visualizador de eventos:

This event is generated when a logon request fails. It is generated on the computer where access was attempted.

The Logon Type field indicates the kind of logon that was requested. The most common types are 2 (interactive) and 3 (network).

The Process Information fields indicate which account and process on the system requested the logon.

The Network Information fields indicate where a remote logon request originated. Workstation name is not always available and may be left blank in some cases.

The authentication information fields provide detailed information about this specific logon request.
    - Transited services indicate which intermediate services have participated in this logon request.
    - Package name indicates which sub-protocol was used among the NTLM protocols.
    - Key length indicates the length of the generated session key. This will be 0 if no session key was requested.
