Domain controller not appearing in DNS on any server but itself?




I have a site with a DC I want to decommission, and a relatively new one (promo'd within the last two weeks). I'm having trouble demoting the old server, and in the process of trying to figure out why I'm running repadmin /replsum on a few of my DCs.



On most of them, I'm getting the error:




Experienced the following operational errors trying to retrieve replication information:



58 - c7908eb4-5ef4-46a7-b445-642b33ece726._msdcs.domain.com





I've looked around in DNS on the rest of my DCs looking for this listing, and I finally found it on my new DC mentioned above, and it refers to itself! So every other DC appears not to know about this DC, at least from a DNS perspective, but running repadmin /replsum on my new DC does not return any errors.



Why would this be happening, and what's the best way to correct it?


Answer



Eventually they all just figured it out, I guess. I took a look a few days later and the relevant DNS entries existed and I'm no longer getting any errors running repadmin.
