Account Lockout Analyzer (ALA) helps you identify the root cause of an account lockout. Whenever an account gets locked out, this feature locates all probable resources (such as services, or mapped drives, or ActiveSync-enabled devices) where the account in question has been configured, so that you can quickly zero in on the source of the lockout and remedy the stale credentials stored in it.
To enable ALA to report ActiveSync and OWA-related lockouts, you must configure IIS logging on the Exchange server which has Client Access Role set up. You should also enable IIS on the server where ADAudit Plus is installed.
You can choose to configure this automatically or manually.
