samba - Apr 2016 - I can not access the DNS via RSAT, access denied

I tried the version 4.2.11 and will not let me access the DNS via RSAT,
I changed several permissions in several ways and does not allow me
access will be a bug?



if i try to browse dns from a windows2003 dns management utility in
log.samba i got the following message:

[2016/04/16 09:39:45.296046,
