Automatic Multicast Session to bare metal workstations

Is it at all possible to do that to a workstation that is just out of the
box (never registered with eDirectory, no OS, no agents etc)

I tried setting a session as per:
http://www.novell.com/documentation/...a/a5uw8r8.html

workstations PXE, connect to Transaction Server & do not find any work

Thanks
