Changing user information on Windows XP in a domain If you’re using Windows XP Professional on a domain, such as in a Windows 2000 Server net- work, you have to configure the users twice in two different places. First, you perform the steps described in the preceding section for creating or changing user accounts on the XP computer. Second, you must create or change accounts in the Computer Management dialog box to match the computer accounts. Basically, you can add finer detail to the permissions in the Computer Management dialog box. To create or change a user in Computer Management for the domain account, follow these steps: 1. Click Start ➪ Control Panel. The Control Panel dialog box appears. 2. Click Performance ➪ Maintenance. The Performance and Maintenance dialog box appears.

3. Scroll to the bottom of the dialog box. Click Administrative Tools. The Administrative

Tools dialog box appears.

4. Double-click Computer Management. The Computer Management console appears see

Figure 13-7. Figure 13-7: Computer Management is for an XP on a domain.

5. Expand Local Users and Groups and select Users. A list of computer users appears in

the right window pane.

6. Right-click the user you want to configure, and choose Properties from the pop-up win-

dow. The user’s Properties dialog box appears see Figure 13-8. Note Chapter 13 ✦ Accessing the Network Figure 13-8: Configuring a user for the domain in XP The options and permissions in this dialog box refer to the domain network. Generally, only an administrator has the rights to configure users. If you do not understand the rights, then don’t make any changes until you’re sure of what you’re doing. To learn more about Windows XP permissions, see www.microsoft.comtechnet. Setting logon preferences in Mac OS X To change user accounts in a Mac OS X computer, you use My Account. Follow these steps: 1. Click System Preferences. The System Preferences dialog box appears. 2. Click My Account. The My Account dialog box appears, as shown in Figure 13-9.

Understanding usernames Your username is the name by which you’re known to your computer andor on the network. You might use your first name, a nickname, or some other identifier. You can use any combi- nation of letters and numbers; uppercase, lowercase, or initial caps; and even spaces within the name. Windows 98 stores each user’s unique identification information in a password list PWL file. The name of the PWL file is the username plus the PWL extension, such as Plumlsj.pwl or Hugh.pwl. The file is stored in the C:\Windows directory. A PWL file contains a user’s passwords for various programs in Windows, including the following: ✦ Resources protected by share-level security, such as a folder on another network com- puter and the password you use to access that folder ✦ Internet Explorer and e-mail program passwords ✦ Any passwords for clientserver networks, including NT Server and NetWare networks, but not primary logon passwords The passwords in a PWL file are encrypted, or scrambled in a code format, so that no one can read them. If a user on the network forgets his or her logon password, you always can delete that user’s PWL file. The file is re-created when the user logs on again; however, the user also will have to enter passwords for a while until the file is totally rebuilt. Deleting the PWL file doesn’t delete the user, the password, or any other important information, just the file that stores information for easy and quick access to programs. A common problem with network users is that they automatically enter the password when their computer starts up without looking at the Username box. If someone else logged on to the network using that computer, the username will be different. Make sure that your users are accustomed to looking at the username before entering the password. If the wrong user- name is listed with the wrong password, access is denied to the network. In Windows XP, there is no PWL file or even an equivalent. XP is based on NT technology, meaning it is a more secure, more closed system. It is important that if you’re using XP, you create at least one user who has administrative rights and keep that user separate from all others. For example, when you first log on to XP, the default is Administrator. You should immediately set up user accounts. You might set up only one user account, but you can set up more. Whether these new accounts are administrative is up to you, but make sure you set up at least one — named ME, SuperPower, Backdoor, or some other name that you’ll remember — that has administrative rights. You can make the password anything you want as well, but make sure you remember it. If you fail to set up at least one administrative account, you’ll be out of luck when you want to make major changes to the operating system if your own account somehow gets locked out.
