Account lockouts not in Event Viewer
Solution 1:
Craig, you are correct it is 4740, however I did search for that before and received nothing. On the Windows 7 client it is 4625.
I found the issue. The Audit Account Lockout policy I mentioned was set to "failure" only. Once I enabled "success" it logged the lockouts with ID 4740. I thought I had tested "success" previously, but after filtering the log for 4740 I only found today's events. The log in Windows 7 must have thrown me off since that one shows 4625 with "failure" and account lockout as the category.
Thanks.
