No, I meant originally, do not run the join command again.

OK, but calling an AD DC 'PDC' is (in my opinion) a bad idea, but you
will now have to put up with it ;-)

A 'PDC' is a totally different thing from an 'AD DC' and as such, can
cause confusion.

You have also posted that you are running a kerberos server on your DC,
you should stop this, the AD DC is also running one.
