Unable to start the Netlogon Service On DC

Question

Hi,

Unable to start the Netlogon service on DC.

We have verified the Netlogon dependencies and observed all are running state only.

Verified the registry value for sysvol ready.

Tried restarting the DC.

Tried forcefully restarting the service using net start netlogon -force command.

Due to Netlogon service we are unable to open the any AD console & unable to start the windows time service.

Looking for any suggestion make me resolve this issue.

Thank you!!

Answer 1

Thank you for your quick reponse.

I wanted to update you regarding the issue we were facing with the computer's naming convention. After a thorough investigation, we have identified that the computer reverted to the workgroup name in the registry. This discovery came as a result of our examination of the system logs, particularly focusing on event ID 6011.

Thank you so much for your response.

Hi SHANTHIRAJ THEETLA1,

Thank you for posting in the Microsoft Community Forums.

Check the status of Netlogon service

Using Command Line Tools: In Windows, you can check the current status of the Netlogon service by opening the “Command Prompt” (run as administrator) and typing the command sc query netlogon. This will show whether the service is running, stopped, suspended, etc.

II. Viewing System Logs

Event Viewer: Open Event Viewer by pressing Win+R, typing eventvwr.msc, and then Enter. Look for error messages related to the Netlogon service in the “Application” and “System” logs under “Windows Logs”. These messages may provide additional clues that the service is not starting.

Confirm the system configuration

Network Configuration: Ensure that the DC's network configuration is correct, including IP address, subnet mask, gateway, and DNS settings.

Domain Name System (DNS) resolution: Verify that the DNS servers are able to resolve the names of domain controllers and clients correctly.

IV. Check security software and firewall settings

Security Software: Ensure that no security software (such as antivirus software or firewall) prevents the Netlogon service from starting.

Firewall rules: Check the firewall rules to make sure that the network traffic required by the Netlogon service is allowed.

V. Try to start the service with administrator privileges

Service Manager: Open the Service Manager by running services.msc and locate the Netlogon service.

Start the service: Right-click on the Netlogon service and select “Start”. If the service fails to start, try right-clicking on it and selecting “Properties”, and in the “Startup type” drop-down menu, select “Automatic (delayed start)” or “Automatic”. “Automatic”, and then click ‘OK’ and try to start the service again.

Forcing the service to start using the command line

Command Line: Although you have tried to use the net start netlogon -force command, please note that the -force parameter is not a standard parameter of the net start command. The correct command should be net start netlogon. if the service still fails to start, you may need to consider other methods.

Resetting the Netlogon Service

Registry Edit: As a last resort, you can try to reset the Netlogon service by editing the registry. However, please note that this involves advanced technical knowledge and may lead to other problems. Always back up the registry before making any registry changes.

Deleting and recreating the service: In some cases, it may be necessary to delete the registry entry for the Netlogon service and recreate it to restore the service. This usually involves using the sc delete netlogon and sc create commands. Note, however, that this method should be used with caution and under the guidance of a professional.

Best regards
