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 depending on the IP settings of the computer.
If I am connected by VPN with an IP address provided by the VPN DHCP service, everything works as expected.
If I am connected to the internal network with the IP address provided by the DHCP service located on one corporate Windows server:
- 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
If I am connected to the internal network with the IP address provided in theory by the DHCP server configured manually on the computer, everything works as expected.
Has anybody experienced the same issue? It seems that the DHCP service is not providing only IP address, netmask, gateway and DNS or that Windows 11 is expecting more information that are currently not configured in our DHCP server.
Thanks in advance
