Hi Everyone,
After the last serveral power failures, when our server came back up, the static entry for our second DC was missing.
Config Info: We are running Server 2008 r2 with three writable DCs and six RODCs. Each server has both DNS and DCHP installed. DNS is active directory intergrated. The three DCs have Primary-Zones and the RODCs have secondary zones. According to each of the WDC they are listed as the primary serverfor DNS Zone under the Start of Autority tab. Scavenging/No-Refresh/Refresh are all set to 7 days.
I have confirmed that there isn't a conflicting DNS Zone as per some of the articles I found on the subject. It appears that the dns entry is being immediately Tombstoned regardless of my re-adding it after manually deleted the entry in ADSIEDIT. I also forced DC2 to register itself (ipconfig /registerdns) to same effect. This Tombstoning effect is occuring very fast (less thatn 15 minutes). I suspect a replication issue.
Is there a config issue behind the problem? We had our domain setup by professionals a few years ago, but this wouldn't be the first major boo-boo they put in our system.
Should only one DC/DNS be the primary server?
Should only one DC/DNS be a Primary Zone with all the other being secondary zones? If they are secondary, can we create new a new primary zone if the first one fails?
Any guidance would be much appreciated.
