Account Lockout Policy

[JMB]

I wonder if anyone can help. As part of our eSafety policy, I tried to set up the "Account Lockout" in GP. Settings were for 6 attempts, and the two time parameters were set to 60 minutes. What actually happened is that locks everyone out. I can unlock them, but if they log out and try to go back in, they're locked. I've since changed the policy back to "not defined" but it's still doing it. Can anyone offer any advice as it's becoming VERY annoying! Thanks! :0(
