I have had some trouble recently with Simple File Sharing, every time I have
tried to disable it, it kept turning back on.
I have tried turning of ‘Guest only’ and use ‘Classic Login’ by pushing the
setting out through group policy
I have eventually found out that the setting (Guest only) was enabled in the
LOCAL Security Policy.

My question is (I know Local Policy overwrites Group Policy) how can I
change the local security policy without having to go round to all the
machines individually?

Is there a reg key I can push out?

Thanks
