Updated: February 28, 2009

Applies To: Windows Server 2008 R2

This topic explains how to use the Active Directory module for Windows PowerShell to modify a fine-grained password policy.

The following example demonstrates how to modify the minimum password length and password history count of the fine-grained password policy DomainUsersPSO:

Set-ADFineGrainedPasswordPolicy "DomainUsersPSO" -MinPasswordLength 8 -PasswordHistoryCount 24

You can use the following parameters when you set many of the common values that are associated with a fine-grained password policy:

  • -ComplexityEnabled

  • -Description

  • -DisplayName

  • -LockoutDuration

  • -LockoutObservationWindow

  • -LockoutThreshold

  • -MaxPasswordAge

  • -MinPasswordAge

  • -MinPasswordLength

  • -PasswordHistoryCount

  • -ReversibleEncryptionEnabled

For a full explanation of the parameters that you can pass to Set-ADFineGrainedPasswordPolicy, at the Active Directory module command prompt, type Get-Help Set-ADFineGrainedPasswordPolicy –detailed, and then press ENTER.
