Script to set folder permissions

Ok I already have a script, using XCACLS.vbs that sets the correct permissions on client folders.

The problem is that in order to run the script on the client machines, they need to have the XCACLS.VBS copied into their Windows directory. And they are all setup as power users and if I create a script to copy the .vbs file to their Windows drive, access is denied.

Does anyone know of a way to get this .vbs file into all clients Windows folders, aside from going to each computer and doing it manually?
