When you clicked on the box and clicked apply, user was unlocked even though nothing happened.<br />
If you close the object properties and open it again, you will see that the user is not locked anymore.<br />
<br />
Why those users were locked out, I really can't tell. Any info in the event viewer?

That didn't appear to be the case I'm afraid. &nbsp;The domain controller I rebooted just has a couple of entries in the App log stating - <br />
<br />
The winlogon notification subscriber &lt;GPClient&gt; took XX seconds to handle the notification event (CreateSession).<br />

How can rebooting a server cause all accounts to lockout??

Our office 2008 domain has 2 domain controllers on it. I needed to reboot one of them and since then users are reporting that their accounts are locked. Sure enough, in AD the option 'Unlock Account' is active but if I select it and ht Apply nothing happens.<br />
<br />
Any idea why this has happened i.e. is there something wrong with my AD setup? <br />
<br />
Thanks
