[libvirt-users] Remote Shutdown of Server 2008

Good afternoon, I have a VM of Microsoft Server 2008 SP1. I am using virsh commands to power it on/off. I can power on/off when the admin is logged in to the Server VM, and when there are no users logged in, but when the admin locks the screen, I cannot seem to power it off. The virsh command states that the domain is being shutdown, but it in fact does not. I looked at some registry settings for the VM (server 2008) and see if I can pinpoint an entry I need to set, but had no luck. Any ideas? Thank you for your support. - Frank G.
