Wed Nov 28 00:56:42 MST 2012

Any ideas/solutions/hints for the DNS Updating Issues?

> What works:
> - Samba4 Server migrated from Samba3 data.
> - adding a 2008_R2 DC.
> - Replication sofar as I could monitor.
> - internal DNS Server on Samba.
>
> What fails:
> Automatic DNS Updates are not working, althought "allow dns updates =
> true" in smb.conf is set - which seems to enable secure AND unsecure
> updates.
>
> Manual adding an Record works on both machines, and it gets replicated on
> both.
>
> I also raised the Domain and Forest Level from 2003 to 2008 R2.
