You would create a subfolder BETA inside the NETLOGON share of your DCs in order to not interfere with the potentially existing login scripts. Then you start with a simple script runnign the executables off the NETLOGON share. Then you expand to bigger, more complicated scripts. Once it all works for some test accounts you can release it into the wild.

And, of course, you should read the KiXtart Manual and the FAQ Forum before starting.
