Brute force protection is a critical security feature in Windows Server 2022 designed to prevent unauthorized access by locking out accounts after multiple failed login attempts. However, there are scenarios where you might need to disable or adjust this feature, such as in controlled testing environments or specific application configurations. In this blog, we’ll walk you through the steps to disable brute force protection in Windows Server 2022, discuss the risks involved, and provide best practices to maintain security.
What is Brute Force Protection?
Brute force protection is a security mechanism that safeguards your server from repeated login attempts by locking out accounts after a specified number of failed tries. The Windows Server Update KB5020282 enables a Feature called “Account lockout for built-in local administrators”, which locks out the Administrator Account after 10 failed password attempts during 10 minutes. However, in certain situations, such as debugging or testing, you may need to disable or modify this feature.
Why Disable Brute Force Protection?
While brute force protection is vital for security, there are legitimate reasons to disable it temporarily:
Testing Environments: In development or testing environments, frequent login attempts might trigger lockouts, disrupting workflows.
Application Compatibility: Some applications or scripts may require multiple login attempts, leading to unintended lockouts.
Controlled Access: In highly secure, isolated networks, brute force protection might be deemed unnecessary.
However, disabling brute force protection should only be done with caution and in controlled environments.
"Securing your Windows Server is not just about locking doors—it's about building a fortress. Every layer of protection, from strong passwords to brute force defenses, ensures your data remains safe in an ever-evolving digital landscape."

Risks of Disabling Brute Force Protection
Disabling brute force protection can expose your server to significant security risks, including:
Increased Vulnerability: Without account lockout policies, attackers can repeatedly attempt to guess passwords.
Unauthorized Access: Weak or compromised passwords are more likely to be exploited.
Data Breaches: Sensitive data on your server could be at risk if unauthorized users gain access.
Best Practices to Maintain Security
If you must disable brute force protection, follow these best practices to minimize risks:
Use Strong Passwords: Ensure all accounts have complex, unique passwords.
Enable Multi-Factor Authentication (MFA): Add an extra layer of security to prevent unauthorized access.
Restrict Access: Limit access to the server to trusted users and networks.
Monitor Logs: Regularly review server logs for suspicious activity.
Re-enable Protection: Once your task is complete, re-enable brute force protection to secure your server.
