[Samba] Reset DACL on Samba Internal DNS

[James]

Hello,

    Is there a command to reset the discretionary access control list on
the internal Samba DNS? Looking over this document

https://technet.microsoft.com/en-us/library/cc756835%28v=ws.10%29.aspx

It shows 'Creator Owner' as having permissions. I'm missing this entry.
I manually added it in the meantime. This is in response to secure
updates no longer working. Thanks.
