Fix Recommendation

Configure the policy value for Computer Configuration >> Windows Settings >> Security Settings >> Account Policies >> Account Lockout Policy >> "Account lockout duration" to "15" minutes or greater.

A value of "0" is also acceptable, requiring an administrator to unlock the account.

Check Contents

Verify the effective setting in Local Group Policy Editor.

Run "gpedit.msc".

Navigate to Local Computer Policy >> Computer Configuration >> Windows Settings >> Security Settings >> Account Policies >> Account Lockout Policy.

If the "Account lockout duration" is less than "15" minutes (excluding "0"), this is a finding.

For server core installations, run the following command:

Secedit /Export /Areas SecurityPolicy /CFG C:\Path\FileName.Txt

If "LockoutDuration" is less than "15" (excluding "0") in the file, this is a finding.

Configuring this to "0", requiring an administrator to unlock the account, is more restrictive and is not a finding.
