copy and register an .ocx

I have about 500 computers I need to copy a file to the system32 directory and register it. Users that log on do not have access to register .ocx files, nor to copy them into the System32 directory. The do have access to the location where the files are stored.

Is there a script that I can run as a different user (administrator) at logon, that will accomplish this.

I'm trying to prevent having myself and my staff go from computer to computer to accomplish this.

We are on a Windows 2000 domain and the majority of my clients are Windows XP. Thanks.
