@LSERVER won't work either.

Here is what I am planning on doing:

We have created a transform of MS Office 2003 so we can burn a CD-ROM to send out to remote users. So we don't break licensing rules, we are planning on putting an encrypted KIX and encrypted ZIP combination together so only machines that are joined to any of our 14 domains can run the script and have the script de-crypt the ZIP (which holds the MFT file), therefore minimizing the chance of anyone upgrading their home machine.
