This article describes how to prevent the last logged-on user name from being displayed.
After you use this method, a user must type a user name and password to log on to a Windows 2000-based computer. The default setting is to remember the name of the last logged-on user and automatically include this name in the logon dialog box. Security administrators may prefer the last logged-on user name not to appear in the logon dialog box. Although this configuration requires users to type their user name each time they log on, it can help to prevent attempts by unauthorized users to gain access to the computer.
You can configure Windows 2000 to remove references to the last logged-in user by using Group Policy. The group policy can apply to the local computers, sites, domains, and organizational units
