Network ID Wizard

If you do not know how to complete these tasks, you can use the Network Identification (ID) Wizard to help you. To start the Network ID Wizard, follow these steps:

1. In the System Properties dialog box, click Network ID.
   
   Note This wizard is new to Windows XP. With this wizard, you can add the computer to a workgroup or to a domain.
2. Move backward and forward in the wizard by using the Back and Next buttons.

The first set of options in the Network ID Wizard is as follows:

• Option 1
  "This computer is part of a business network, and I use it to connect to other computers at work."
• Option 2
  "This computer is for home use and is not part of a business network."

If you select option 1, the following options appear:

• Option 1a
  "My company uses a network with a domain."
• Option 1b
  "My company uses a network without a domain."

If you select option 1a, a dialog box appears that requests the following information:

• User name
• Password
• User account domain
• Computer name
• Computer domain

If you select option 1b, you can also configure the computer as a "Workgroup Member," and you can type the name of the workgroup.

If you select option 2, you are prompted to click Finish to restart the computer. If you follow this step, the computer is configured as a "Workgroup Member." By default, the name of the workgroup is "Workgroup."

Then, the next page requires the domain name to which the computer is to be added. Also, the next page requires the username and the password of an account that has the rights to add a computer to the domain. Additionally, the next page enables the user account from the previous page to be added to this computer. Finally, the next page enables the new user to have various rights on the local computer.

The user may be added to the following built-in groups on the local computer:

• Administrators
• Backup operators
• Debugger users
• Guests
• HelpServicesGroup
• Network configuration operators
• Power users
• Remote desktop users
• Replicator
• Users

Note If the computer is a member of a domain, the computer also maintains a local domain that has security accounts. These security accounts only pertain to that computer. To change domains at the logon screen, press CTRL+ALT+DELETE. If the Domain box does not appear, click the Options button to display the Domain box, and then select the required domain from the menu.

Note Generally, you must have Administrator credentials on the computer to complete the tasks that are mentioned in this article.
