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.

Display name:Netlogon
Service name:Netlogon
Service type:share

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.

Dependencies

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

Restore Default Startup Configuration for Netlogon

1. Select your Windows 8 edition and update pack, and then click Download.

2. Save the Win8_Netlogon_Service_Startup.cmd file to a local storage device.

3. Run the saved file as an administrator.

4. Restart the computer.

The Netlogon service is using the netlogon.dll file that is located in the %WinDir%\system32 folder. If the file is corrupted or deleted, you can put it back in there.
