Hello I am currently testing the compatibility of our organization with Windows 11 and I am facing a strange behavior. The DNS service is not working well with Windows 11. On Windows 10 there is no issue and all the IP addresses are resolved correctly from our DNS, but on Windows 11, the DNS results are strange: If the request belongs to our main domain, nslookup provides the correct internal IP address If the request belongs to an internal domain only, nslookup provides the correct internal IP address If the request belongs to any other domain, nslookup provides the public IP address instead of the internal IP address This is only happening from the internal network. If I connect by VPN, using the same DNS servers, then the result is correct in every case. Has anybody experienced the same issue? Is this a problem of the Windows 11 desktop, the DNS server...? Thanks in advance Best regards Yann

Dear all I have found a solution that solve my issue but generate a bigger concern. I have just tried to configure manually the network connection of the laptop, using exactly the same IP address, mask, gateway and dns server that I was getting before from the DHCP server. And it works! Like this the DNS is correctly providing the internal IP address instead of the external one. If I then configure back the network through DHCP, it fails again. It looks like if the DHCP server is giving more information than just the IP configuration. Has anybody experienced this kind of issue? Thanks in advance Best regards Yann

The issue is that it is perfectly working for all the computers and my laptop just started this strange behavior after the upgrade to Windows 11.

Regardless, it is an age old very well known issue when the internal domain name is the same as public domain. --please don't forget to upvote and Accept as answer if the reply is helpful--

Hello @Yann Dublanche This may have a very simple solution: A) verify that both Primary and Secondary DNS are set to Domain DNS servers B) Flush DNS records and re-register the computer: from CMD as admin: ipconfig /flushdns ipconfig /registerdns Run a "ipconfig /displaydns" to ensure that the proper resolvers are configured.

I am experiencing the same issue on Windows 11. When i am in the office my device gets ip address, subnet and dns servers from DHCP and all works ok. When i leave the office and connect at home, my device gets the ip address and subnet ok but DNS doesnt update. If i do an IPCONFIG i can see the DNS servers set as the ones from when i was in the office, even though it is set to get it from DHCP. The only way to get it to get the DNS from DHCP is to uninstall the NIC driver and reinstall but this occurs every time. I never experienced the same issue on Windows 10.

DNS Client Configuration:

Check DNS Server Settings: Ensure that the correct DNS servers are configured in the network adapter settings.

Disable IPv6: Temporarily disable IPv6 to isolate the issue.

Flush DNS Resolver Cache: Run ipconfig /flushdns to clear the DNS cache.

Firewall and Security Settings:

Firewall Rules: Check if any firewall rules are blocking DNS traffic.

Antivirus Software: Temporarily disable antivirus software to see if it's interfering.

Windows 11 DNS Client Bug: Windows Updates: Ensure your Windows 11 installation is up-to-date with the latest patches.

Microsoft Support: Contact Microsoft support for specific troubleshooting steps and potential bug fixes.

DNS Server Configuration:

DNS Records: Verify that DNS records are configured correctly for both internal and external domains.

DNS Server Health: Check the health of your DNS servers to ensure they are functioning properly.

By systematically checking these aspects, you should be able to identify and resolve the DNS issue

I experience the same issue here, DNS Server remains the same, dispite the fact that the DCHP server should provide one

We are experiencing a very similar issue in an enterprise deployment. Windows 10 is fine at that same network whereas Windows 11 doesn't resolve all queries for internal networks. Seems to have no issue resolving external queries but are set to internal DNS. It's very strange.

This answer is too complicated for a home user. The system always discovered the DNS automatically. It is only this recent update that has caused a problem. Microsoft needs to fix the update so that the machine always discovers DNS automatically

Hello @Yann Dublanche

This may have a very simple solution:

A) verify that both Primary and Secondary DNS are set to Domain DNS servers
B) Flush DNS records and re-register the computer:
from CMD as admin:

ipconfig /flushdns
ipconfig /registerdns

Run a "ipconfig /displaydns" to ensure that the proper resolvers are configured.

Hope this helps with your query,

Hello

Thanks a lot for the answer. Unfortunately, it is not solving the issue.

One strange things is that in the displaydns, I see this result that correspond to the computer name but not the correct domain:

computername.mshome.net
----------------------------------------
Nombre de registro . : computername.mshome.net
Tipo de registro . . : 1
Período de vida . . . : 536774
Longitud de datos . . : 4
Sección . . . . . . . : respuesta
Un registro (host). . : 172.18.64.1

Best regards

I am experiencing the same issue on Windows 11.

When i am in the office my device gets ip address, subnet and dns servers from DHCP and all works ok.

When i leave the office and connect at home, my device gets the ip address and subnet ok but DNS doesnt update.

If i do an IPCONFIG i can see the DNS servers set as the ones from when i was in the office, even though it is set to get it from DHCP.

The only way to get it to get the DNS from DHCP is to uninstall the NIC driver and reinstall but this occurs every time. I never experienced the same issue on Windows 10.

Have you found a resolution to this? I have the same issue. My work network provides a DNS server, but until I switch from manual DNS back to auto DNS, my laptop does not pull the proper DNS settings for the work network. It's crazy that such a basic, flawed behavior is happening and I can't find a solution anywhere. Even finding posts where people describe the same issue are tough to find.
