ok...
can I ask, are you wanting to do this via logonscript or adminscript?

the difference is that with logonscript you most likely need to expose admin password.
and in worst case, distrib even a domain-admin account.
in admin script the script is ran by your rights by you and it uses your rights when connects to the clients and executes what ever command you wish.
like, timed SP install.

admin script might be little harder to come up with but there is always that question about security...
