I recently upgraded my domain from 2k3 to 2k8 and my DC's are failing dcdiag /test:dns

I had no failures when I demoted the old domain controllers or errors when I brought them back up as 2k8's.  I had 5 DC's that were all named AD1-5 and I demoted them one at a time, reinstalled, and promoted back to DC's named AD1-5.  Attached is my dcdiag report.

do you have DNS installed on that specific DC ?

i guess that 216.55.150.242 is the ip of the second DC ?

How do I automatically generate the AAAA records for itself?  It is AD1.

rather, since I'm not using IPv6, how do I get it so that it is disabled and DCDIAG doesn't report it as errors?
