Trouble with Windows 11 Upgrade: Domain Joined Machines Showing Public Network and GPO Issues
Asked by

I'm facing a peculiar problem after upgrading several domain-joined machines from Windows 10 to Windows 11 (25H2) via ISO. After the upgrade, these computers are showing their network as "unauthenticated" and categorized as Public. I've tried a networking reset which resolved the "unauthenticated" label, but the machines are still not recognizing the domain network correctly and GPOs are failing to apply. Other freshly built Windows 11 machines are working without issue. I'm getting messages that there's no connectivity to the domain controller despite being able to ping and access them remotely after tweaking the firewall. I've checked with NLTEST, which recognizes the correct domain controllers, and removing/re-adding them to the domain works without a hitch. IPv6 is disabled, and I can access the machines' shares just fine. I'm unsure if this is a networking or a GPO issue. If anyone has suggestions, I'd greatly appreciate it!

Have you confirmed that the domain trust is still intact? You could use a PowerShell command like `Test-ComputerSecureChannel` to test it out. If it returns false, some additional commands might be required to fix it.

This seems like it might be a Network Location Awareness (NLA) issue. Have you checked the registry at `HKLMSOFTWAREMicrosoftWindows NTCurrentVersionNetworkListProfiles`? I'm curious about what it shows there.

Are you using 802.1x authentication in your organization? If so, this could be affecting your network connections.
