MORE INFORMATION
By default, users who do not have administrator rights and permissions
cannot change power scheme settings. The power schemes program changes both
per-user and per-machine settings. To change the per-machine settings, you
must have administrator rights and permissions. Failure to set the
per-machine settings prevents the per-user settings from being committed.

Therefore, if you are a user who does not have administrator rights and
permissions, and you try to use the power schemes program in Windows XP to
change the power scheme settings, you receive the following error message:
Power Policy Manager unable to set active policy. Access is denied.

Create a Group Policy object to change power scheme settings
To create a Group Policy object to change the power scheme settings, follow
these steps:1. On the domain controller, copy the Powercfg.exe file to the
NETLOGON share.• By default, the Powercfg.exe file is located in the
%systemroot%\System32 folder on a Windows 2003-based computer.
• By default, the NETLOGON shared folder is located at
%systemroot%\Sysvol\Sysvol\Domain_DNS_name\Scripts on a Windows Server
2003-based computer.

2. Click Start, click Run, type dsa.msc, and then click OK. This starts the
Active Directory Users and Computers snap-in.
3. In the Active Directory Users and Computers dialog box, right-click the
domain container, and then click Properties.
4. On the Group Policy tab, click New.
5. Type Power Configuration Policy, and then press ENTER.
6. Click Edit.
7. Under User Configuration, expand Windows Settings, and then click Scripts.
8. In the right pane, double-click Logon, and then click Show Files. The
user’s \Scripts\Logon folder appears.
9. In the user's Scripts\Logon folder, create a new batch file that sets the
power scheme settings on the user's computer. To do this, follow these
steps:a. Click File, click New, and then click Text Document.
b. Type PowerConfig.bat, and then press ENTER.
c. In the Rename dialog box, click Yes.
d. Right-click PowerConfig.bat, and then click Edit.
e. If an Open File - Security Warning dialog box appears, click Run.

net use x: \\domain_DNS_nameetlogon
x:
powercfg.exe /change "always on" /monitor-timeout-ac 20
powercfg.exe /SETACTIVE "always on"
c:
net use x: /delete

Note The domain_DNS_name term that is used in the batch file is a
placeholder for the DNS name of the domain controller.
g. Click File, click Exit, and then click Yes.

10. Close the Scripts\Logon folder.
11. In the Logon Properties dialog box, click Add, click Browse,
double-click PowerConfig.bat, and then click OK two times.

Group, type the user's domain name and account name in the User and group
names box, and then click OK two times.

26. In the Active Directory Users and Computers dialog box, click File, and
then click Exit.

Note The first time that the user logs on to the user's computer, the policy
will fail because the other rights and permissions have not taken effect. The
second time that the user logs on to the computer, the policy is applied, and
the user has permission to change the power scheme settings.

Configure user access to power settings
To deny permission to change the settings modified by the logon batch file,
configure user access to the PowerCfg.cpl file. You can deny permission for
the user to open the Power Options extension in Control Panel to view or to
change the power settings. To do this, follow these steps:1. Click Start,
click Run, type dsa.msc, and then click OK. This starts the Active Directory
Users and Computers snap-in.
2. In the Active Directory Users and Computers dialog box, right-click the
domain container, and then click Properties.
3. Under Computer Configuration, expand Windows Settings, and then click
File System.
4. In the Group Policy Object Editor dialog box, click Action, and then
click Add File.
5. In the Add a file or folder dialog box, type
%SystemRoot%\system32\powercfg.cpl in the Folder box, and then click OK.
6. Click Add, type the user's account name in the Enter the object names to
select box, and then click OK.
7. In the Permissions for user name access permission group, click to select
the Deny check box for Full Control permission, and then click OK.
8. In the Security dialog box, click Yes.
9. In the Add Object dialog box, click Configure this key then, then click
Propagate inheritable permissions to all subkeys, and then click OK.

Tengo un problema y es el siguiente.

Tengo equipos XP que por defecto tienen para el disco duro tras 20 minutos
de no usarlos. El problema es que cuando el equipo reintenta arrancar el
equipo tras tocar el ratón se queda pillado (debe ser alguna incompatibilidad
del fabricante con windows o ves a saber) con lo cual la solución es decirle
que no apage el disco nunca.

Pues bien, si lo hago como administrador local, al entrar el usuario del
dominio no guarda la configuración y lo deja en 20 minutos. El usuario por
defecto no tiene permisos y no se lo puede cambiar, con lo que tengo que
darle permisos de administrador, cambiarlo y luego quitarselos...

En GPOs no encuentro la política o plantilla para aplicarsela a todo el
dominio... alguien sabe donde tengo que tocar? Gracias
