Netlogon Service Defaults in Windows 7

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.

Startup type:Manual
Display name:Netlogon
Service name:Netlogon
Service type:share
Error control:normal
Group:MS_WindowsRemoteValidation
Object:LocalSystem
Path:%SystemRoot%\system32\lsass.exe

Default Behavior

Netlogon is a Win32 service. In Windows 7 it won't be started if the user doesn't start it. When the Netlogon service is started, it is running as LocalSystem in a shared process of lsass.exe. Other system components, such as drivers and services, may run in the same process. If Netlogon fails to start, Windows 7 attempts to write the failure details into Event Log. Then Windows 7 startup should proceed and the user should be notified that the Netlogon service is not running because of the error.

Dependencies

Netlogon is unable to start, if the Workstation service is stopped or disabled.

2. Save the Win7_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 lsass.exe file that is located in the %WinDir%\system32 folder. If the file is changed, damaged or deleted, you can restore its original version from Windows 7 installation media.
