I can't make the ADC join the domain.
I have set the DNS entries for DC and ADC to the same IP address.

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:

  1. 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,

  1. 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
