Yes... you can now install the MOM 2005 SP1 Agent on Windows XP Embedded
The MOM 2005 SP1 Agent Prerequisite Component for Windows XP Embedded installs the necessary components that support the MOM 2005 SP1 Agent on Windows XP Embedded. This allows you to then install the MOM 2005 SP1 Agent and monitor the health of Windows XP Embedded in the same way as you monitor the health of other Microsoft operating systems. These devices include, but are not restricted to, point of sale (POS) terminals, automated teller machines (ATMs) and Windows-based thin clients.
When installed on the machine running the Target Designer, the MOM 2005 SP1 Agent Prerequisite Component adds the necessary Windows XP Embedded components to your Component Database. After you have installed an image created with this component, you will need to deploy the MOM 2005 SP1 Agent separately.
