DCDIAG Error



Sometimes Exchange 2007 had problem connecting to the DC (cannot find DC) I
then started to run a dcdiag and got some DNS errors which I think I fixed.
Now when I run a DCdiag it passes all the test without one of which I have
attached the log from DCDIAG below. I have no idea what that could be.
Could anyone please point me to the right direction. I really would
appreciate.

Thanks in advance.
