What is Event ID 4740?
Event ID 4740 is generated whenever a user account is locked out—typically after repeated failed logon attempts.
This event logs key data such as:
- Locked account username and domain
- Caller machine name where the attempts originated
- Lockout timestamp and security IDs
This event captures lockouts on domain controllers, servers, and workstations
Why Monitoring Event Code 4740 Matters
Account lockouts aren’t just user errors—they can signal threats or operational issues:
- Detect brute-force or password-spray attempts
- Uncover service misconfigurations using outdated credentials
- Identify source systems triggering repeated failures
- Reduce IT downtime and helpdesk costs
- Support compliance with NIST, PCI DSS, HIPAA, GDPR, ISO 27001ManageEngine
According to Verizon DBIR 2024 "70% of breaches begin with compromised credentials"
—making event codes like 4624 your only early clue.
