Windows 2000/XP/2003 contains several ADM files. These files are text files, called Administrative Templates, that provide policy information for items in the Administrative Templates folder in the control tree of the Group Policy Management unit.
In Windows 2000/XP/2003, the default Admin.adm administrative templates are located in the INF folder of the system folder, and contain four template files from the default installation: Policies, for system settings. In "Policies" for Internet Explorer (IE) policy settings.

In the Policy Management Console, you can add "policy templates" several times, let's take a look at the specific operation:
First run the "Group Policy" program, and then select "Computer Configuration" or "User Configuration" under the "Administrative Templates", click the right mouse button, select "Add/Remove Templates" command, and then in the open dialog box, click "Add/Remove Templates". Click the "Add" button in the dialog box that opens, and select the corresponding ADM file in the dialog box that opens. Click the Open button to open the selected script file in the System Policy Editor and wait for the user to execute it.
A GPO is a physical policy associated with a domain, address, or organizational unit. On NT 4.0 systems, a single system policy file (e.g., ntconfig.pol) includes all of the policy functions that can be enforced, but it is dependent on the settings in the system registry on the user's computer. In Win2K, GPOs include files and AD objects. With Group Policy, you can specify registry-based settings, local computers running Win2K using NT 4.0-formatted .adm template files, security settings for domains, and network software installations using the Windows Installer so that folders can be redirected when software is installed. The Group Policy Editor (GPE) plug-in in the Microsoft Management Console (MMC) is comparable to the System Policy Editor poledit.exe in NT 4.0. Each functional node in the GPE (e.g., Software Settings, Windows Settings, Management Module, etc.) is an MMC plug-in extension. Extensions are optional management tools in the MMC plug-in, and if you're an application developer, you can expand the functionality of the GPO with customized extensions that will provide additional policy control for your application. Only systems running Win2K can enforce Group Policy. Clients running NT 4.0 and Windows 9x will not recognize or run GPOs with an AD architecture.
