Joining another DC shouldn't do anything to the old DC (except add the
new DC's info), so it looks like you have something wrong.

So, we know that the new DC is running 4.5.12 on Debian, but what
version of Samba is running on the old DC and what OS is it ?

Can you post the following files, from the old DC and the new one: 

/etc/hostname
/etc/hosts
/etc/krb5.conf
smb.conf

If you are using Bind9, post the named conf files.

You can sanitise the files if you wish, but if you do, use the same
names everywhere.
