You're using a lot of abbreviations, so I'm not 100% sure what exactly your problem is.
There's always a few things you can check, though:
- Make sure that the joining machine can resolve your domain successfully, i.e. entering
nslookup the.domain
in a command shell should return the IP address of the existing domain controller.
If it succeeds, but you still cannot join,
- Make sure that the relevant ports for a domain controller are reachable from the joining machine, the most important being 53/tcp, 53/udp, 88/udp, 135/tcp, 445/tcp, and 1024-65535/tcp. documentation

the solution : there is no connection between the machines because of the virtual machine is NAT adapter and to ping it should be a Bridged – Amany Ashraf Oct 24 '22 at 17:43
