Distribute Local GPOs

I need to distribute a local GPO created in MMC to all W2K Pro machines on the network. We are running an NT server Domain, so no AD at present.

What would work best? Script? Login script?
Secedit utility or gpupdate utility?
Just copy the files from the Group Policy folder to all W2K desktops??

Any help will be appreciated! We are ostly applying IE settings and desktop lockdown policies.
