Netlogon Service Defaults in Windows 8

Maintains a secure channel between your computer and the domain controller for authenticating users and services. If this service is stopped, the computer may not authenticate users and services and the domain controller cannot register DNS records. If this service is disabled, any services that explicitly depend on it will fail to start.

Default Settings

Startup type: Manual
Display name:Netlogon
Service name:Netlogon
Service type:share
Error control:normal
Registry key:HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Netlogon

Default Behavior

Netlogon is a Win32 service. In Windows 8 it will not be started until the user starts it. When the Netlogon service is started, it runs as LocalSystem in a process of lsass.exe, sharing it with other services. If Netlogon fails to start, the error details are added to Windows 8 error log. When the operating system startup is complete, the user is being notified that the Netlogon service hasn't been started.


Netlogon can't start, if the Workstation service is disabled or not available.

Restore Default Startup Configuration of Netlogon

Before you begin doing this, make sure that all the services on which Netlogon depends are configured by default and function properly. See the list of dependencies above.

1. Run the Command Prompt as an administrator.

2. Copy the command below, paste it into the command window and press ENTER:

sc config Netlogon start= demand

3. Close the command window and restart the computer.

The Netlogon service is using the netlogon.dll file that is located in the C:\Windows\system32 directory. If the file is removed or corrupted, read this article to restore its original version from Windows 8 installation media.
