I think most of the Domain Administrator know how to set the logon script for individual users, but have you wonder how to set it for all the user altogether to use the same script without having to edit the user one by one and change the logon script?
I found 1 script that able to do a little bit help on that and can get from here, you can run this script from any pc that is a domain member with domain administrator rights. Then run the following command:-
updatelogonscript.bat <logon script>
It will add the logon script to all the users you have on your domain.
