You are missing the msdcs.domain.com zone.

https://www.experts-exchange.com/questions/24349599/URGENT-MSDCS-records-registering-directly-under-FWD-lookup-zone-not-under-FQDN-name-space.html

This is only DC for my domain, can creare problem remove msds and domain zone?
This resolve dcdiag problem also?

Thank you very much! You are really a genius!
