Hi Rowland,

I followed this page 
more than once.
Everything in here is fine...every test successful.

My problem is that the existing SAO record is pointing to 
dc1.samdom.example.com which doesn´t exist anymore.
Now it must be dc01.samdom.example.com.

What happens when I try to add ...
samba-tool dns add _msdcs.samdom.example.com @ NS 
dc01.samdom.example.com ... ?
will it break something because we still have an entry..even it´s a 
wrong one ?
