I have been seeing these errors show up in the server logs recently. I have run dcdiag and all the tests pass, on running netdiag the DNS test fails saying can't find an authoritative DNS server for our server. It says it is not correctly registered on server 0.0.0.0. Running IPconfig /all shows the DNS server with the correct IP address. Both the DNS server and the DC are the same server. Running netdiag /fix does not work it can't register with the DNS server. I have attached a DNSlint report which may help. Thanks.
