A server administrator implements a new account lockout policy to prevent improper escalated access for all of the privileged accounts. After 24 hours, several scheduled tasks and backups fail to comp

Reverting the policy immediately might resolve the issue but could reintroduce the security risk and doesn't provide insight into the root cause of the failures.

Blocking the policy on impacted servers is a reactive measure that bypasses security controls and does not help in understanding the problem's underlying cause.

Identifying and reenabling locked accounts is a corrective action that should follow the diagnostic step of reviewing logs to confirm the cause and frequency of lockouts.

Reviewing security logs, potentially in a SIEM, is the most appropriate first step as it provides crucial diagnostic information without making further changes that could introduce new risks or disrupt systems. This allows the administrator to identify exactly which accounts are being locked out and on which servers, narrowing down the scope of the problem.
