Dhcp is not updating dns in server 2016

Here's a Power Shell script that lets you easily test for multiple different problem scenarios. Ensure dynamic updates are enabled on the DNS zone This is less likely to be the problem because all clients would not be working is the dynamic updates setting on the DNS zone. If set to Secure, you may begin to see more instances like the ones we'll be talking about in #4 below. Check permissions on the dns Node AD object This problem in particular was extremely hard for us to track down on one occasion.

Check the DNS client service of the new computer The DNS client service is the service that does the actual update.

If this service is stopped for some reason no update will proceed.

Previously this was done by attaching a second NAT router with firewall behind the router that connected my home from the internet.

With the ERL (in combination with a managed switch) I can instead use VLANs to separate my networks for something that looks more like this: In these posts we’ll gradually work towards setting up the Edge Router Lite for this setup.
