Script for ghosting PC

I am using norton ghost 6.o for imaging of PC’s,Ghost is instaleld on one of our server,Administartor will login this system start ghost session to format any pc,and at client end we generally boot thru ghost boot fdd,which will ask me session name ,tht is given on server than starts formatting pc,i want a script tht will start a sesion on network and format pc,so that user can directly format pc with distrubing administrator,in other works Ghost is running on one server and image is there in that server hdd,i want to write a script in such a way that session should start from client pc and image shd be loaded,without user accessing server.
