Account Lockout is not working

I have setup a GPO with an account lockout of 1.
Applied the GPO to the OU with one workstation.
Yet the computer is not locking out after one attempts.
What am I doing wrong?

Create a local user on that computer and try it with his account, it should work.
Dynamic did you edit your reply while I was replying? Didn't see a mention of local accounts on your at first.
Yup and make sure you are not blocking inheritance on your Domain Controllers OU. I had this problem in production trying to apply this at the OU level, and it took me about a week to figure out why it wasn't working
Thanks,
