Скачать или смотреть Windows Server 2025 - Public Network Profile Fix for Domain Controllers

While working with Windows Server 2025, I encountered an issue that has affected previous versions of the OS as well: the persistent Public profile issue, which may impact domain controller functionality since your DC(s) don't believe they're on a domain network.

I created this video to provide a simple steps for resolving the problem, in case you've also ran into it. Thanks for watching!

UPDATE 12/19/2024: I've updated the PowerShell script (follow the Github link in the description) where there's now a 60 second sleep timer added before the network adapter is restarted. With the task set to ruin right at startup, there's a chance all the DC's services may not be started before the NIC is reset which can cause the fix to not work properly.

If you experience issues with the script, please bump in the -Seconds to additional increments of 60 seconds to match what works best for your server in your environment. You may have to go higher if your server takes a very long time to boot.

^ If you would like you can also start the service up afterwards and/or reboot to see if your issue has resolved. I did not go over this in the video as it didn't resolve my issue either of my DCs despite hearing others having luck online.

1:45 Scheduled Task to Reboot NIC Adapter on Boot
3:00 Running the task manually

Steps mentioned in the video:

------------------------------------------------------------------------------------------------------------------
Disable NegativeCache registry settings (the time that a client remembers that a domain controller can't be found)
------------------------------------------------------------------------------------------------------------------

Set-ItemProperty -Path "HKLM:\SYSTEM\CurrentControlSet\Services\NetLogon\Parameters" -Name "NegativeCachePeriod" -Value 0 -Type DWORD

Set-ItemProperty -Path "HKLM:\SYSTEM\CurrentControlSet\Services\Dnscache\Parameters" -Name "MaxNegativeCacheTtl" -Value 0 -Type DWORD

---------------------------------------------------------------------------------------
Set Network Location Awareness Service to not immediately give up upon not finding a DC
---------------------------------------------------------------------------------------

Set-ItemProperty -Path "HKLM:\SYSTEM\CurrentControlSet\Services\NlaSvc\Parameters" -Name "AlwaysExpectDomainController" -Value 1 -Type DWORD

-----------------------------------------------------
Set the NLA Service to Automatic
-----------------------------------------------------
Open Services
Right click the NLA Service
Set startup type to automatic

--------------------------------------------------------
If all of the above still doesn't work
--------------------------------------------------------
Create a scheduled task to restart your NIC adapters as soon as the OS boots
