Problem to setup DNS server on Windows Server 2016

Try setting it all up but for the domain name just use something like:

ad.komplex.pl

Hopefully, that should sort your issue out.

Unfortunately it does not working.

When I want to join domain I see this error:

I can't join domain beacuse DNS Name dont exist.
I think, I dont have "_ldap._tcp.dc._msdcs.ad.komplex.info.pl" because "query concerns the SRV record for _ldap._tcp.dc._msdcs.ad.komplex.info.pl"

One or more zones do not contain delegation to the child zone:

ad.komplex.info.pl

komplex.info.pl

info.pl

ok

.(Main zone) 

Try removing the DNS role and then reboot and re-add it.

Configure your DNS server to use a static Internet Protocol (IP) address. - Yes, 192.168.88.201
Create a forward lookup zone named after your Active Directory. - I have attach it.
Enable your domain zone to allow dynamic updates. - I have attach it too.

netdiag /fix - doesn't work. I have attach it.

I used "dcdiag /fix" and here what I have:

C:\Users\Administrator.SERVER2016AD.004>dcdiag /fix
