Hello,
I've got a simple 2 node Server 2012 cluster and have configured CAU. It actually runs the updates just fine, but something is not quite right.
When I run Server Manager, it lists the "entity" (I don't know what to call this thing - it's not a server, but it's listed here) that was created when I enabled CAU with the name CAUhvcluxc4 with an error of "Target name resolution error." I tried adding a CNAME DNS entry for CAUhvcluxc4 to point to the name of my cluster, and that caused the error to go away, but it started generating errors in the FCM saying "dns rr set that ought not exist does exist."
I'm sure there's something simple I'm doing wrong here, but I can't figure it out.
