Assuming you have admin rights on that local computer or access to an account you could do the following:
launch an mmc (if you have to change accounts, then use runas from a cmd line to launch the mmc)
You can add the Group Policy snap-in from File, Add/Remove Snap-in
Choose `Group Policy Object Editor" and click Add
Change it from Local Computer by clicking "Browse" and then clicking "Another Computer" and typing in the name of the remote computer
As far as running a script...sure, but you'd have to be a lot more specific as to how you want to connect to the computers, whether you want it to run once remotely or at login, scheduled, etc. etc. etc.
