Set computer name in dvd/cd boot imaging

Hi.
We have NW 6.5.3/Zen D Managemnet 7 i our head office. Here everything works
ok
with P.X.E. and policy.

In remote offices we want to do an image of new work stations with a dvd/cd
boot.
But we can not find a way to set the computer name ?????
We dont want to ask the user to change the computer name manually after
imaging.

Do we have to buy other imaging software to fix this? My hope is ZDM 7 have
a
switch for this in some script ??

Still hoping .......................
