Server 2008R2 account lockouts not being logged

I enter 3 incorrect passwords on a terminal server using the RDP client.  3 Audit Failures appear in the security log on the terminal server.  
On the sole DC at that site there is no lockout event logged in the security log nor any audit failures yet the account is locked out.

A user's account is getting locked out and I need to trace the source (the device which caused the account to become locked out).  The user only connects to that Terminal Server yet the account seems to be being locked out from elsewhere as there are no audit failures prior to the lockout on the Terminal Server.

I am seeing a few event 4625 in the security log on the DC but very few and not in the above scenario.

I am looking for the steps in order to trace the source of AD user lockouts.  I also would like to see the audit failures on the DC when authentication fails.

Here is the audit policy on the DC.

Try if adding the policy

Computer Configuration -> Windows Settings -> Security Settings -> Advanced Audit Configuration -> Logon/Logoff -> Audit Account Lockout: Success, Failure

I would highly recommend using Active Directory Auditor by Lepide Software.

From there you will be able to pin point exactly where/why/how the account is being locked out.

Here is one nice run through to isolate the more likely culprit machine

Hence may want to consider the toolkit "Account Lockout and Management Tools" to  assist in managing accounts and in troubleshooting account lockouts as below.
ALoInfo.exe. Displays all user account names and the age of their passwords.

•EnableKerbLog.vbs. Used as a startup script, allows Kerberos to log on to all your clients that run Windows 2000 and later.

•EventCombMT.exe. Gathers specific events from event logs of several different machines to one central location.

•LockoutStatus.exe. Determines all the domain controllers that are involved in a lockout of a user in order to assist in gathering the logs. LockoutStatus.exe uses the NLParse.exe tool to parse Netlogon logs for specific Netlogon return status codes. It directs the output to a comma-separated value (.csv) file that you can sort further, if needed.

•NLParse.exe. Used to extract and display desired entries from the Netlogon log files.
Has Powershell sent you back into the Stone Age?

If managing Active Directory using Windows Powershell® is making you feel like you stepped back in time, you are not alone.  For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why.

Thank you all for your posts.

Computer Configuration -> Windows Settings -> Security Settings -> Advanced Audit Configuration -> Logon/Logoff -> Audit Account Lockout: Success, Failure
is what was used to change the auditpol settings to "Success and Failure" for logon and lockout.

While I am sure a 3rd party tool will work I would prefer to use the software we already paid for to accomplish this.

I have used lockoutstatus however it does not show the source of the lockout beyond the DC which I already know.  EventcombMT is only useful if the events appear in the security log which they do not.

Some setting is not set to log these account lockouts - the group policy settings are not doing what they describe.  My guess is Microsoft changed something with those group policy settings and how they apply on the DC and there is now some other setting I need to set to get this information into the log.

Any further help would be much appreciated.

Tef beloe link it stated very similar issue and the miss reason is user failed to enable Audit User Account Management.

Also this may already be know, if you need to enable/disable auditing in Active Directory, you need to change the default Domain Controller's policy, not the domain policy. This is because the auditing is done on the DCs and it is the default Domain Controller's policy that governs policy on DCs. Likewise, possible can restart which I believe you already done so too...

Thank you.  User Account Management did resolve the issue.  The event is logged as 4740 "User Account Management".  That brings the question of what the "Account Lockout" logging does but I now have what I need.

It lists the source as the remote RDP client and does not indicate which terminal server the connection was made to but this will work.  Much appreciated.
