How To Use the Group Policy Editor to Manage Local Computer Policy in Windows XP

Uses of Group Policy

In Microsoft Windows XP, you use Group Policy to define user and computer configurations for groups of users and computers. You create a specific desktop configuration for a particular group of users and computers by using the Group Policy Microsoft Management Console (MMC) snap-in. The Group Policy settings that you create are contained in a Group Policy Object (GPO), which is in turn associated with selected Active Directory containers, such as sites, domains, or organizational units (OUs). With the Group Policy snap-in you can specify policy settings for the following:

• Registry-based policies.
  These include Group Policy for the Windows XP operating system and its components and for programs. To manage these settings, use the Administrative Templates node of the Group Policy snap-in.
• Security options.
  These include options for local computer, domain, and network security settings.
• Software installation and maintenance options.
  These are used to centrally manage program installation, updates, and removal.
• Scripts options.
  These include scripts for computer startup and shutdown, and user logon and logoff.
• Folder redirection options.
  These allow administrators to redirect users' special folders to the network.

With Group Policy, you can define the state of users' work environment once and rely on the system to enforce the policies that you define. 

How to Start the Group Policy Editor

To start the group policy editor, follow these steps.

NOTE: You must be logged on to the computer using an account that has administrator privileges in order to use Group Policy Editor.

6. If you do not want to edit the Local Computer policy, click Browse to locate the group policy object that you want. Supply your user name and password if prompted, and then when you return to the Select Group Policy Object dialog box, click Finish.
   
   NOTE: You can use the Browse button to locate group policy objects linked to sites, domains, organizational units (OU), or computers. Use the default Group Policy Object (GPO) (Local Computer) to edit the settings on the local computer.

   The selected GPO is displayed in the Console Root.

How to Use the Group Policy Editor

The Group Policy snap-in contains the following major branches:

• Computer Configuration
  Administrators can use Computer Configuration to set policies that are applied to computer, regardless of who logs on to the computers. Computer Configuration typically contains sub-items for software settings, Windows settings, and administrative templates.
• User Configuration
  Administrators can use User Configuration to set policies that apply to users, regardless of which computer they log on to. User Configuration typically contains sub-items for software settings, Windows settings, and administrative templates.

To use the group policy editor, follow these steps:

1. Expand the GPO that you want. For example, Local Computer Policy.
2. Expand the configuration item that you want. For example, Computer Configuration.
3. Expand the sub-item that you want. For example, Windows Settings.
4. Navigate to the folder that contains the policy setting that you want. The policy items are displayed in the right pane on the Group Policy Editor snap-in.
   
   NOTE: If no policy is defined for the selected item, right-click the folder that you want and then on the shortcut menu that appears, point to All Tasks, and then click the command that you want. The commands that are displayed on the All Tasks submenu are context sensitive. Only those commands that are applicable to the selected policy folder appear on the menu.
5. In the Setting list, double-click the policy item that you want.
   
   NOTE: When you work with policy items in the Administrative Templates folder, click the Extended tab in the right pane of the MMC if you want to view more information about the selected policy item.
6. Edit the settings of the policy in the dialog box that appears, and then click OK.
7. When you are finished, quit the MMC.
