samba - Mar 2015 - ad dc demotion fails trying to use non-existent dc as 'partner server for the4 demontion'

I'm trying to demote dc3 from msad dc service.


As the root user, I type this command:

  samba-tool domain demote -Uadministrator


which fails with this error:

"Using dc2.infinity.local as partner server for the demotion"


The problem is that dc2 was demoted some weeks ago, and is no longer running
samba4.


Is there a way I can force dc3 to use a different dc as the 'partner
server'?


Or, is there a way I can clear dc2 out of the memory of dc3?


Or, would it be better to treat dc3 as though it were non-functional, and remove
it from dc service via another way - e.g. the script mentioned
here<https://wiki.samba.org/index.php/Demote_a_Samba_DC#Demote_a_DC_that_isn.27t_accessable_any_more>?


Thanks

Was dc2 successfully demoted? If yes, you should check, if your
replication is working. Maybe not all DCs got that information
replicated for some reason.

# samba-tool domain demote --server=...

As far as I could tell, dc2 was successfully demoted.  I don't recall any
errors when I demoted it.

Furthermore, it was not anywhere I could see in ActiveDirectory Users and
Computers or Sites and Services.  Not in the DNS Manager.

However, the problem is now solved: I recreated dc2, added it as a dc, and then
I was able to demote dc3, and after that demote dc2.

So, in the end all is well.

Regards,

Jon
