We are running server 2008 r2 and have an account lockout duration setup in group policy. Originally it was set for 30 min. but we changed it to 99000 minutes. We've made the change several weeks ago but accounts are still using the old 30 min. lockout duration time. I ran a rsop on several computers and they show they are using the new lockout duration time, but the accounts are still being unlocked after 30 min. Below are the settings we use. Any ideas?
Account lockout duration 99000 minutes
Account lockout threshold 3 invalid logon attempts
Reset account lockout counter after 5 minutes
