This comes up often and I can never find everything in one place. This is a good post with a bunch of info and links.
We migrated our domain to 2008 AD from 2003 AD last week and found a couple of issues via SCOM.
- DNSSec Zone TrustAnchors - for this one you’ll get an alert that looks like this: Zone TrustAnchors on DNS Server dns.name is not responding to queries.
- DNS 2008 Server External Address Resolution Alert – for this you’ll just get a failure of the alert. To be fair the same alert for 2003 has the same problem, but we had fixed that a long time ago, thus the info had been forgotten.
