Update the deployment agent service to subscribe to WM_POWERBROADCAST messages. This would allow the service to notify the deployment server when a workstation is about to change power states.

When a SUSPEND message is received, the agent can notify the server to change its state so that it appears properly in the console as powered off, in stand-by, or on; the agent could also set the SetThreadExecutionState to prevent the workstation from entering a suspend mode if a task is in progress. Conversely, is the agent receives a RESUME message, if can notify the server to change its state so that is appears properly in the console as powered on.
