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.

Darius GhassemCommented:
Keep IPv6 enabled on SBS 2008 server you can cause some other issues what you can do is move IPv4 higher in the binding order. Make sure your SBS server only points to itself for DNS in the TCP\IP properties. Plus setup DNS Forwarders.

DNS forwarders were the culprit - thank you.  Sorry for the delay in response.
