When NLA starts to detect the network location, the machine will contact a domain controller via port 389. If this detection is successful, it will get the domain firewall profile (allowing for correct ports) and we cannot change the network location profile.
If the domain was not found or process failed, NLA will let you to determine which firewall profile will be used, private or public.

So I'd check the domain controller and problem client have the static address of DC listed for DNS and no others such as router or public DNS

Thanks for the quick response DSPatrik.

Unfortunately this issue was created due to windows update happened on 9th Nov 2022 to all DC, we are getting unauthenticated error because of Kerberos key generation to all the client machines.

Solution: I found the solution in one of the other forum that, we need to add below registry keys to DC, our issue got resolved immediately.

reg add "HKLM\SYSTEM\CurrentControlSet\services\kdc" /v KrbtgtFullPacSignature /t REG_DWORD /d 0 /f

reg add "HKLM\SYSTEM\CurrentControlSet\Services\Netlogon\Parameters" /v RequireSeal /t REG_DWORD /d 0 /f

reg add "HKLM\SYSTEM\CurrentControlSet\services\kdc" /v ApplyDefaultDomainPolicy /t REG_DWORD /d 0 /f
