Server 2016 r2 dns not updating
Installing the DNS Server does not require a restart, but unless you've planned for the downtime, keep that box unchecked, just in case.If you are an old pro with DNS server files, Windows Server 2012 does let you edit the files directly.Microsoft Windows Server 2012 is a powerful server operating system capable of many different roles and functions.
Do not allow unsecured dynamic updates unless you really know what you are doing and have a very good reason for doing so. If your DNS server ever gets a query for which it has no record, it can forward that request on to another DNS server to see if it has the answer.
To setup and configure DNS, one must install the DNS Server Role on Windows Server 2012.
Click Next on the Add Roles and Features Wizard Before you begin window that pops up.
The order forwarders are listed in is the order they are tried, so place your faster and most reliable forwarder at the top of the list.
Click Next and your DNS server is now configured and ready for use.
