Screen Saver Is Not Password-Protected When You Apply the "Password Protect the Screen Saver" Group Policy Setting
Article ID: 815424 - View products that this article applies to.
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:
The "Password protect the screen saver" Group Policy setting is set in the following registry entry:
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
ScreenSaverIsSecureregistry entry is a REG_DWORD (numeric) value. Other operating systems, including Windows Server 2003, Windows 2000, and Windows XP SP1, store
ScreenSaverIsSecureas 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.
