How to restore _msdcs and all subfolders in dns server 2008?

Question

Domain Name System

Hello! I've read everything, tried everything, but nothing comes out.
Is available Server 2008 Enterprise, Active Directory. I say right away that
initially it was not me who set it up, I inherited it. There is
one domain, there are no backup domain controllers. According to the stories, earlier user authorization went without problems, but something happened and the last admin tried to fix DNS, but nothing happened. I found a missing _msdcs in the forward lookup zone. To restore, I did the following: manually created _msdcs.domain_name, then performed dcdiag / fix, ipconfig / registerdns, net stop netlogon && net start netlogon, net stop dns && net start dns. DNS registered in AD, read manuals from Microsoft, did everything according to
instructions. They write that the _sites, _tcp, _udp subfolders should
recover themselves, but no (This is my first experience of configuring dns, while reading
the manuals I figured out a lot of things, but I feel like I’m missing something, I’m stupid. Accordingly, at first the domain was not seen at all, and now after all my measures, it is visible and asks for an administrator password to enter the computer into the domain, but writes that the network path was not found.I checked the properties of the network adapter as they say, it is in the first place and registration of the address of this connection is allowed.All additional information is on the screenshots, including the required tests. Accordingly, there are no subfolders (dc, domains,gc,pdc) for _msdcs and subfolders for domain_name.com (_msdcs,_sites, _tcp,_udp).
