Did you also change the MAC address for the network adapter in the VMWare settings? Otherwise VMWare believes (and possibly your network too) the two machines are the same. After changing the MAC address, reconfigure your network settings on the clone and reboot. Delete the trust (computer) account for the original machine from Active Directory. Then retry the net join command for both machines.

Once the machine is clone I changed the IP address, hostname in (/etc/hosts and /etc/hostname) and also changed the name in /etc/samba/smb.conf Finally I tried to join the clone machine using “net join –U administrator” unfortunately this break the original freeradius machine by no longer authenticating to active directory and the clone machine will not join the Domain also. I think the clone machine is still referring the original machine which breaks the original machine unfortunately I do not know how to fix it. How do I fix the original machine? What else do I change on the clone machine so that I can successfully join it to domain with breaking the original machine?
