DCDIAG /TEST:DNS FAILS

Good morning.  Please help me interpret the results of my DCDIAG failure.  This is post a migration from SBS 2003 to SBS 2008.  I ran the test because I am having a problem with OLD dns records (duplicate ips for multiple hosts in DNS manager)

Thank you for your input!!

Unless you have a need for it, start by dissabling IPv6 on all interfaces.

DNS forwarders were the culprit - thank you.  Sorry for the delay in response.
I have a similar problem! Do you think you can give me a hand?
