- After you clone a VM, you need to make sure you leave the domian before connecting it to the network so you don't have any conflicts. The VM must be renamed and rejoined. Otherwise you will have issues.
- You can only be part of ONE domain at a time, this is an Active Directory design consideration. Hence the need for trusts in merge/acquisition situations. In your case, since there's no trust, you will be saying goodbye to the old and hello to the new. If the old stays, users will be prompted for re-auth each time they need to access resources.
Just so you know, this is my last response to this thread due to other activities.
