Hi,
The process of the DAgent/AClient/ADlagent is to connect up and check on the serverside, if there is a job scheduled for the client - or possibly be part of an initial deployment job.
Thus you can't really by default tell the dagent to run a job from the client side. Having said this, there are some tools (axsched) that would allow you do probably do somehting along those lines with some scripting.
Perhaps describe what happens now and what you're wanting to happen would make it easier to give some better advice.
