RE: Policy enforcement- Admin accounts

Many people have replied to the original post, stating to set an additional
GPO on an OU, so you can set a different password policy.

I agree, yes can go ahead and create a GPO, assign Password Policies in it,
and link it to your OU - but, the password policies will NOT take affect...

I repeat, the Password Policy portion of a GPO can only be applied at the
domain level... This could be in the 'Default Domain Policy' or in a new GPO
applied to the domain, but it only applies at the domain level.

That is why I, and several others, suggested the only viable option is to
create an additional management domain in the forest. It can be an empty
root with just your admin accounts. THEN, you can apply different password
policies to the admin users the management domain...

Wow thanks, I didn't know that. I remember that we could use passprop, but
didn't try to use it on the
2k3 domain...

Thanks for the update :)

Charles is correct in regards to the inability to set password policies on
an OU basis.

He is not correct in regards to the default domain Administrator account not
being able to be locked. Please consult the following MS article, which
describes how to configure the domain\administrator account to lockout using

Charles Hardin is absolutely right, on this subject, you cant set 
password policies with OUs.. :( thats why, security professionals 
advising the administrators, to disable the "admin" account (even 
rename it) and then use another account with the "admin" privileges. 
after you have yourself that kind of an account you can set the 
account lockout policy for it..
unfotunately password policies are set domain wide.

As Charles Hardin mentioned below, moving your accounts to another 
domain, should establish a trust between your domain and admin domain, 
so that management would not be a problem...

Sadly with AD you can only have one account security policy per 
domain. You would need to make a second domain in your forest and 
move your admin accounts there. Also remember the actual 
Administrator account CANNOT be locked out.

In an active directory environment (windows 2003), I want to ensure

attempts to brute force account password. The flipside is, we might 
have a DoS
but I can live with it. Is there a tool I can deploy to ensure that
account also locks out after certain no. of attemps?

Also, ONLY for admin accounts, I want to enforce certain settings like:
Password should contain atleast 15 characters, should not contain a 
dictionary word etc.
My normal password policy for AD user accounts, set at the domain 
is a
minimum of 8 chars but I want to deploy this special policy of 15 
chars minimum for admin accounts.

How should I go about this?
