Good day!

I can't understand this message:

The DNS entry NS _msdcs.BEO.IMP dcs3.BEO.IMP, queried as
_msdcs.BEO.IMP. does not exist
need update: NS _msdcs.BEO.IMP dcs3.BEO.IMP


On the DC domain controller (Windows Server 2008 R2) there is an entry in
DNS - *_msdcs.beo.imp*

See attachment "dc-samba-dns002.jpg"

What do I need to do to fix the problem?
