Also, Regarding the queue.
The Altirisagent generates an event for everything and puts it in a subfolder of C:\Program Files\Altiris\Altiris Agent\Queue coinciding with your server name. If the server is up and you have connection to it, then the events are delivered in short order.
In our case, Swap computers and various other inactive computers are fully powered on but lacking a network connection. They generate days, weeks or months of events. When they are reattached to the network, they get and run new policies but any inventory or status of such events takes its place at the end of the queue. Because its a laptop with an aggressive sleep timeout, the system suspends before the queue empties.
