Joe,
I don't see that executable on any client machine...did landesk deprecate it perhaps? Is there an advantage to using that over shutdown -r? I think I may be beating a dead horse and have to go with a provisioning template (or a dreaded (by me) Landesk script) to more directly control the reboots and the like. I was really hoping there would be a solution that would allow multiple-package installation when the machine requires a reboot by raising some flag that caused the machine to reboot and made LDMS aware that a reboot was happening prior to attempting to install the "main package" in a multi-package software distribution...maybe I'm hoping for too much.
