This is a DNS server *not* a member of domain.  I removed this from
both dc0, and dc1.

They both are the same now as in your example above.

This is corrected. I would have to look back into my notes to discover
why wrong keytab was used.

Now, for something interesting.  If I create a user on dc1, it shows up
right away on dc0.  If I create user on dc0, it does *not* show up at
all on dc1.

I am using Microsoft 'Active Directory Users and Computers' from
Windows 10 to add users.
