In an active directory environment (windows 2003), I want to ensure
lockout for administrator accounts also, in order to protect against
attempts to brute force account password. The flipside is, we might
have a DoS situation but I can live with it. Is there a tool I can
deploy to ensure that admin 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
level 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?
sounds like you want to create to group policy objects. one a standard
for the domain and one for the administrators. Personally I'd do this
by putting the administrative users in an OU called admin for instance
and creating a personalised GPO and apply it to that OU. Then create a
standard one and apply that to the domain
I'm not sure if it will restrict the use of including words within the
passphrase however iirc it will restrict them from using part of their
username etc.

has more details.
I would suggest testing the strength of account passwords yourself. I
used to run a password cracker at my old workplace, got some choice
passwords and to be honest if you go to a user and show them how easy it
is to guess "asdfgh" etc they often respond.
hope that helps.
