There are various 'samba-tool' commands you can run:

'samba-tool ldapcmp' which will compare the databases
'samba-tool drs showrepl' which shows replication status
'samba-tool drs relicate' which will replicate NCs between DCs

Just add '--help' on the end of the samba-tool for more information.

It might just be easier to demote 'Identity-c01' and then set up a new
DC, but if you do this, do not use the same hostname & IP.
