The user your jobs run as is not a member of any domain, therefore it
has access to not resources obtained through domain membership.
Essentially you have all the CPU and memory on the machine and that's
it (if it's SMP it's up to you to behave rather than launching many
The samba domain controller will essentially be unused from the
execute machine point of view.
What happens when a user logs onto the box is up to the configuration
on the box (I assume under your control)
This however will behave exactly as it does on Unix with the exception
that you should not just assume that users should make their jobs
checkpoint so you can just kick them off since on windows this is not
so easy, you may wish to experiment with suspending jobs for a while
rather than just vacating them.
For windows specifics take a look at
And perhaps take a look at the archives for several threads from Ian
Chesal and myself talking about various aspects of the windows
implementation and how to go about trading off security for wider
domain access (also in the manual search for 'net use'). (there are
some other posts concerning the possibility of using the domain
controller and making the temporary users part of the domain - but I
would advise against bothering with doing that unless you have no
