[Samba] Removed old DC, now replication hopelessly broken [HELP]
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
[root at larkin26 ~]# samba-tool drs showrepl

And advice would be most welcome!

Not sure what fixed it.Stale DNS cache? that seems likely. -- With best regards, Andrey Repin Monday, April 13, 2015 00:31:14 Sorry for my terrible english...
