Nothing wrong with that totaly agree, with both you guys.
And thanks mathias for that MS DNS bug note, i'll have a look into that,
and found fixed in server 2003.. that i missed that.. :-/
The setup i suggested it not only for replication/preventing island problems.
It can also be a major dns performance improvement, which i also noticed.
And maybe this was also something in samba what changed i dont know (yet).
This was an update from 4.4.3 to 4.4.5 in my case also.
And i changed my resolving setup at the same time and since i run it
as is now, i notice much better performance in the complete network, and user noticed it also.
This also forces all registration to go to a single DNS server where it is registered and then replicated to the other servers, which i prefer.
But hee. As mathias says.. its all our own choice.
I noticed it so i mention it and maybe it helps someone.
Greetz,
Louis
