You are the administrator of 10 Windows XP Professional computers for your company. The computers are members of a Windows 2000 domain. Because the computers are used in a public area in the cafeteria, you audit all security events on the computers. A user named Marc reports that he was using one of the Windows XP Professional computers when the computer suddenly shut down with a STOP error. When the computer restarted, Marc attempted to log on by using the same user name and password that he used before. Marc received the following error message: "Your account is configured to prevent you from using this computer. Please try another computer." Marc states that he did not do anything to cause the STOP error to occur. You want to ensure that Marc can use this computer.
