Most of the users on my Active Directory use the same password. How can I restrict them of this? Can I use a GPO?

My first questions would be:

  1. How do you know what passwords your users are using?
  2. Why are they using the same one?

If this is some simple dictionary word password, I suggest just expiring the users' passwords and upping the complexity requirements to force a change.

How do I implement the complexity change? I think there password passes the complexity test. – Haim Bender Nov 30 '09 at 11:38

There isn't any way to stop different users using the same password. The best you can do is force each user's password to expire to get them to change it.
