As i have a parent - child domain in my network as the parent is situated in other geographical location and they both are connected via VPN as i was working on a Bare metal backup & restore process and suddenly found out that after taking backup of child domain and restoring it on a separate hardware which i did not connect to the same network of the parent.
(Note : the restoration was successful)
The issues i faced after restoring is mentioned below. (Note : i did not connect it to the same network as of the parent).
After restoration process we found out the Active Directory, DNS & DHCP were fully functional.
We found some issues with the active directory, As we could not create a new user account or computer object in the Active Directory
The existing domain user accounts could not login in to the workstation.
Does the parent connectivity is required after restoration of the child domain ??.
Really would appreciate if someone would shed some light on this matter.
