I'm building a standalone server for a small network, only one server, 2012 r2. Once I finish following the AD creation and server promotion wizards, and a DNS server is created as part of the process, I later discover within the DNS mgmt console two DNS servers listed. One is named with just the server name, and the other is the fully qualified server name with complete domain suffix.
I have uninstalled AD and demoted the domain controller and then recreated the domain, etc several times during some bench testing of this new domain, but all has gone very well with no glitches, etc that I have noticed. Also, the last time this problem occurred, it seems that the second entry wasn't apparent immediately following the domain / dns creation, but when I revisited the server the following day the second server was now listed.
I'm stumped, any help appreciated.
