[Samba] Can't access DNS from RSAT

[Taylor Hammerling]

The user is a member of "Domain Admins" so they should be able to access
the DNS (as is evident by the fact that they can access the DNS thru RSAT
on the initial DC).
But just to be thorough I have added "Domain Admins" to the group
"DnsAdmins" and tested again, still get the "access denied" error from
within windows.
