Are there changes to the authentication options from 2008 to 2012 like when
they dropped (well, undefaulted) NT authentication? You might find that the
new servers aren't allow the registration to happen successfully.

Yeah, we have over 150 servers (mostly VMs, these days). I don't want to
create static DNS records, that is just something else to remember to delete,
when the server gets retired or renamed ... especially when the servers should
quite easily just register themselves in DNS, as they always have done, up
until this point.

Yeah, it's baffling, I come in this morning, and there are like 2 dozen or more
servers I have to register in DNS again, for some reason.
