Active Directory: Customize the Password must meet complexity requirements

Posted on 2010-09-01
Last Modified: 2012-05-10

I am looking to customize the Password must meet complexity requirements option in AD 2003 and 2008.  

We need to take out the Non-alphabetic characters from this policy.  

does anyone know how I can change the DLL for the policy?  and do you have instruction?

You change this in the group policy setting.  Usually in the default domain policy object.  Through group policy management console.

You can configure the password policy settings in the following location in the Group Policy Object Editor:

Computer Configuration\Windows Settings\Security Settings\Account Policies\Password Policy

If you’re on a stand-alone machine (no AD etc) and dealing with only local accounts, you can enable/disable the policy from:

Administrative Tools -> Local Security Policy -> Account Policies -> Password Policy.

Have a look at KB from microsoft

So you won't just be able to take the non-alphabetic characters out.  You will have to disable password must meet complexity requirements (in the domain linked GPO that others have mentioned)

Unless you feel like writing your own passfilt.dll, you'll have to resort to 3rd-party tools like "Password Policy Enforcer" ( or "Specops Password Policy" (

If you want to attempt to do it yourself (if you have a strong programming backgorund) start here
 I've personally never tried it.

An example is here (requires free registration); should still work with W2k3:
Enforce Custom Password Policies in Windows

But note especially the "Before you implement" section on page 2:
"Consider the following issues before you start coding your own Password Filters:
* Expect the unexpected. Because LSA loads password filters during start-up, if something goes wrong, your system may become inoperable or go into deadlock. To avoid this, develop and test your DLLs on machines that have at least two operating systems installed.

And if you're comparing DIY with prices for a 3rd-party tool, don't forget to take into account how much it costs if your AD comes to a grinding halt because of a malfunction in the filter (and who'll have to take all the blame for it).
