Two weeks ago I wrote the 'Demote a DC' HowTo
(https://wiki.samba.org/index.php/Demote_a_Samba_DC#Demote_a_DC_that_isn.27t_accessable_any_more).

While doing researches and testings for the HowTo, it turned out, that
currently there seems to be no way (samba-tool or the usual Windows
ways) to demote a lost DC and cleanup the metadata.

I created a bug report about that:
https://bugzilla.samba.org/show_bug.cgi?id=10595

I guess the only way would be to manually find the stuff inside the AD
and remove it manually via ldbedit. But I really would be afraid of that!

An other idea I had, would be to temporary join a machine with the same
name/IP as DC and then demote it with samba-tool. After that maybe less
directory entries have to be removed (like the ophaned objectGUID
entries). But this was just an idea and I wanted to try it in my test
environment. But I think it would be a risky way and should be not
recommend.

I think this is a very serious problem/bug!
