SYMPTOMS

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-based computer, 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 Windows Server 2003, Microsoft Windows 2000, or Windows XP SP1, the policy is not applied 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.

CAUSE

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 ScreenSaverIsSecure registry entry is a REG_DWORD (numeric) value. Other operating systems, including Windows Server 2003, Windows 2000, and Windows XP SP1, store ScreenSaverIsSecure 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.

WORKAROUND

Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:

To work around this problem, turn on the local password-protection setting for the screen saver by editing the registry. To do so:
  1. Click Start, and then click Run.
  2. In the Open box, type regedit, and then click OK.
  3. Locate and then click the following registry key:
    HKEY_CURRENT_USER\Control Panel\Desktop
  4. In the right pane, double-click ScreenSaverIsSecure.
  5. In the Value data box, type 1, and then click OK.
  6. Quit Registry Editor.

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section. This problem was first corrected in Microsoft Windows XP Service Pack 2.

MORE INFORMATION

When you install Windows XP SP1 or the hotfix that is documented in the following Microsoft Knowledge Base article, the ScreenSaverIsSecure Group Policy setting is changed to a REG_SZ value.
318449  (http://support.microsoft.com/kb/318449/EN-US/ ) PowerPoint Slide Show Turns Off Screen Saver and Ignores System Group Policy
The hotfix that is documented in this article permits Windows XP client computers to correctly interpret the ScreenSaverIsSecure registry entry regardless of whether it is stored as a REG_DWORD or a REG_SZ value. This eliminates any inconsistencies that may occur when policies are created or edited on different operating systems.
