Netlogon Service Defaults in Windows 10
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 Behavior
Netlogon is a Win32 service. In Windows 10 it is starting only if the user, an application or another service starts it. When the Netlogon service is started, it is running as LocalSystem in a shared process of lsass.exe along with other services. If Netlogon fails to start, the failure details are being recorded into Event Log. Then Windows 10 will start up and notify the user that the Netlogon service has failed to start due to the error.
Dependencies
Netlogon cannot be started under any conditions, if the Workstation service is disabled.
