DNS problem on Windows 11

Question

Good morning, i have a brand new laptop with windows 11.

Until now i have used linux and mac computers.

I have a Mikrotik router that is used for firewall (to the fttc router) and dns server (to have the resolution of the names of my lan servers, routers, and so on).

On this router i've set a list of static IPs (as told before) on the dns server (for the lan server, for the internet it asks to my internet provider's dns server).

My problem is: on the linux and mac boxes, it works like a charm.

On the windows laptop only the internet dns resolution works, the internal servers are not resolved.

Is there a way to solve it?

Thank you.

Answer 1

My WIFI router uses a .HOME suffix for internal DNS names. My laptop uses DHCP, so everything gets set in the network to handle that. Do an nslookup on your internal IP's and see if registers the machine name or machine name dot something. Like my Blackhole.Home.

You may need to add an entry to the DNS Suffix Search List using ncpa.cpl. Or remove the suffix from your router.
