Windows XP machines fail to shutdown when using an Inactivity element.
There is a known bug with Windows XP that when the screensaver is active the machine will not accept shutdown commands.
Disable the screensaver on the machines running Windows XP.
NOTE: Microsoft no longer supports Windows Server 2003, Windows XP, Exchange 2003, or Office 2003/XP. This means that while systems running these products may work with Desktop Authority, these configurations are no longer actively tested or supported by Technical Support. References to these products are retained in the documentation and still appear in the UI for the convenience of customers still transitioning from these products. All references will be removed in the next release of Desktop Authority. Although Desktop Authority may be able to manage desktops with these unsupported products the Management Console can no longer be installed on Windows 2003 Server.
