Computer Configuration\Administrative Templates\System\Net Logon Description
This policy setting configures whether the domain controllers to which this setting is applied will log the new, enhanced domain-wide NTLM logs. These logs contain more information about NTLM authentication on a domain-wide level, including NTLMv1 usage. If enabled, domain controllers will log the new domain-wide NTLM logs. If disabled, domain controllers will not log the new domain-wide NTLM logs. If not configured, domain controllers will default to logging the new domain-wide NTLM logs. More information is available at aka.ms/ntlmlogandblock.
