Is there any way to enable DST on a large group of XP systems?

Is there any way to enable DST on a large group of XP systems? If I manually change the "DisableAutoDaylightTimeSet" value to "0" (in the registry), the data for the values "DaylightBias" and "DaylightStart" automatically update. However, when I run a .bat file to turn on the "DisableAutoDaylightTimeSet" switch, the data changes to "0", but the other two values do not change.
Other users seem to have the same problem; apparently, the way Daylight Savings Time is controlled isn't exclusively through this one Registry setting. DST needs to be enabled or disabled through the Date/Time control in the Control Panel. Failing everything else, it would be possible to write a VBScript to automate the actions of enabling or disabling Daylight Savings Time.
