If we had a domain name names xyz.com working as dhcp and DNS as well.
We created an offline domain that is exactly the same name, same ip, same dhcp and DNS settings. Recreat the list of all computers and users from scratch.
If we take the first domain offline and replace it with the new one. Will the clients machine can login right away. Or should we join them to the new Domain which is also called xyz.com with the same IP like the last one ?
