DNS ISSUES

I just upgraded my AD from 2003 Server to a new 2012 R2 server, process went well all roles show for new Server. However I seem to have some DNS issues, I have entries for the old 2003 server x.x.x.100 in DNS. I ran DCDIAG alone and all good, I then ran  DCDIAG DNS TEST and I have multiple errors:
