[Samba] Removed old DC, now replication hopelessly broken [HELP]

[Adam Tauno Williams]

I removed a DC using the DC removal tool mentioned in
http://gallery.technet.microsoft.com/scriptcenter/d31f091f-2642-4ede-9f97-0e1cc4d577f3
 as https://bugzilla.samba.org/show_bug.cgi?id=10734 prevents normal DC
demotion.

The DC was still all over in DNS, so I had to pick it out.

Now replication between the remaining three DCs is broken

And advice would be most welcome!
