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,
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:
When the value is set to 0
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.
