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!!

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?
