You are a security administrator for your company. The network consists of a single Active Directory domain. Servers run either Windows Server 2003 or Windows 2000 Server. All client computers run Windows XP Professional.
The company’s written security policy states that user accounts must be locked if an unauthorized user attempts to guess the users, passwords.
