I had a user today ask, "Are we still doing the password security program? It’s been over 90 days since we first implemented it and I haven’t been prompted to change my password. Thanks!"
The next thing I said was, F$@%! Then I use most of a script I found at http://msdn2.microsoft.com/en-us/library/ms974598.aspx
This helped me to determin when user passwords expire in an OU.
BTW the user above had changed their password 43 days ago, they had just forgotten!
