You may experience one or more of the following symptoms when you apply the "Password protect the screen saver" Group Policy setting to Windows XP and Windows XP Service Pack 1 (SP1)-based computers:
  • When you create or edit the policy on a Windows XP-basedcomputer, the policy is not applied correctly to Windows XP Service Pack 1(SP1) client computers.
  • When you create or edit the policy on a computer with Microsoft WindowsServer 2003, Microsoft Windows 2000, or Windows XP SP1, the policy is notapplied correctly to Windows XP client computers.
For example, if you enable the "Password protect the screen saver" Group Policy, and you view the screen saver settings of the client computer (right-click an empty area of the desktop, click Properties, and then click the Screen Saver tab), the On resume, password protect check box is selected as expected, but the screen saver is not actually password-protected.
The "Password protect the screen saver" Group Policy setting is set in the following registry entry:
HKEY_CURRENT_USER\Software\Policies\Microsoft\Windows\Control Panel\Desktop\ScreenSaverIsSecure
When the value is set to 0 (zero), password protection for the screen saver is turned off. When the value is set to 1, password protection for the screen saver is turned on.

In Windows XP, the
registry entry is a REG_DWORD (numeric) value. Other operatingsystems, including Windows Server 2003, Windows 2000, and Windows XP SP1,store
as a REG_SZ (string) value. This type mismatch can cause Windows XP client computers and Windows XP SP1 client computers to misinterpret the policy setting.
