Logonscript for macs in a Windows domain

Do anyone know how I can get my macs to run a script at logon?
I need the script to be launched at logon from a location on the domain controller. How can I do this? It needs to be launched for users who have not logged on that mac before as well as users who have done so.

Any help?

Does this help?

Thanks, but not really. I was merely wondering how I can set the machines up to run a script at logon. I know how to do this locally - at an “each user” level, but I would prefer to have it set on the domain controller so that any and all macintosh users have the script(s) run at logon automatically.
