I've created a new GPO for enforcement of a new policy requiring more complex passwords. I've applied the policy at the domain level and set it to be enforced. Unfortunately, it seems like it's hit-or-miss whether the policy actually takes effect on individual computers, and I'm unable to determine what the issue is.
Originally I ran a gpupdate /force on one of the problem clients, and gpresult and RSOP both show that the policy *should* be taking effect, but they're not (at the user level). Obviously the password policy is under the Computer Configuration section, but is there some reason that *some* clients are enforcing this policy while others aren't? All computers have the Windows XP Firewall disabled, as I thought that would be an issue.
I've even tried to dis-join and re-join the computers to the domain, hoping it would kick-start any policy enforcement that it didn't enforce previously.
Please let me know if you'd like any further information, and what you're looking for specifically. I've tried searching on this before, but I can't find any information pertaining to my problem.
