I take by 'nodes' you mean 'AD DC', if not, please describe what you 
mean by 'node'

  two nodes versions 4.15.5 and two nodes is 4.15.0 when add

I think you are going to have to describe your set up a lot better.

What are the AD DC's ? Samba or Windows ?
If they are Samba, are you using the Samba internal dns server or Bind9 ?
Is there any other dns servers being used ?
Are the clients using a DC as their first nameserver ?

Anything else you think may be relevant.
