samba - Dec 2003 - setting domain user types on all workstations

I have a domain I recently setup with 15 2000/XP clients. I have one account I
want to be
an admin on any workstation I login to, a few accounts I want to be power users,
and the
rest I want to be regular users. Can I automate this or do I have to go around
to each
client and add the domain users in 'Users Accounts' control panel and
set their user types?
