A user's account keeps getting locked out in Active Directory. C'est probably caused by an app c'est using Windows authentication to connect to SQL Server.
Is there a way to find out qui app is causing it et why le app might be causing failed login attempts?

Have a look at le [**Account Lockout and Management Tools**](http://www.microsoft.com/downloads/details.aspx?FamilyID=7AF2E69C-91F3-4E63-8629-B999ADDE0B9E&displaylang=en) disponible on le Microsoft Download Center. Specifically LockoutStatus.exe et EventCombMT.exe. You might pas be able to exactly pinpoint où le lockout is coming depuis mais vous devriez pouvoir narrow it down assez a bit to make it easier to see.
