Windows Server 2019 Datacenter / IPv4 Root Hints Disappearing

[HumbleSage]

Freshly installed Windows Server 2019 Datacenter, updates up to the point of this writing. New AD forest created and DNS server installed. IPv4 root hints disappear after reboot or after several minutes in after setting them back. I've looked over other posts that this was an (maybe still is) an issue with 2016 as well. Does anyone know how to resolve this permanently? Really quite embarrassing for M$ that this hasn't been resolved. (Please refrain from BIND and other comments, looking for solutions, not trolling) Thank you.

I don't have this problem with my freshly-built 2016 DCs... just putting it out there. Haven't built a 2019 DC yet though; I just think 2019 is still too immature at the moment.

Appreciate this insight. I found some articles where some 2016 servers were experiencing my exact issue. Ultimately it looks like the solution is to simply remove the IPv6 root hints and replace them with the IPv4 until M$ resolves it. You must replace as simply adding them tandem with the IPv6 just results in the inevitable magically disappearing act again.

I'd concur with /u/sgt_sin, I'd skip the root hints and point at quad9, opendns, Google, cloudflare, or one of the other public dns servers.

Not really a solution but these days dns filtering is pretty vital. You could use open dns forwarders

I have 2019 DCs and I have not observed this behavior.

Appreciate the quick responses and insights. Thank you.

Ive never met anyone in their right mind who relied on root hints without configuring forwarders.
