Copying the Guests group

I'd like to create a group in 2000/XP that basically mirrors the
Guests group. Ideally I'd like to copy the Guests group directly, but
assuming that's not doable...

How do you determine the permissions that are assigned to the Guests
group?

Assuming you had that set of permissions, is there a way to
programmatically assign them to a new group?

Thanks
