I have network where I have had two DNS servers (they are Doman Controllers as well). Now I installed new DC to our domain and demoted the oldest one. I installed DNS as well for this new DC and I removed DNS from this old one. After this all our network doesnt work anymore. I did dvdiag /test:dns and here are results. There is mention about bbad server but that one is very old test server and it hasnt been in our network since very long time. So its not probably the problem.
