You might think you are stuck with it, but unless you plan to upgrade to 
Samba AD, you might find you are stuck without it. NT4-style domains are 
going away, in fact they were deprecated at 4.13.0

It is your decision, but I felt that I should warn you.

Ensure that all the Samba daemons are stopped, then try this '[global]' 
section of the smb.conf:

[global]
         domain master = No
         security = DOMAIN
         client min protocol = NT1
         template shell = /bin/bash
         winbind use default domain = Yes
         workgroup = HOME
         idmap config * : range = 3000-7999
         idmap config * : backend = tdb
         idmap config HOME : range = 10000000-19999999
         idmap config HOME : backend = rid

Try the join again and if it joins, then start winbind followed by smbd 
and nmbd.
