How can we increase to Kerberos - what would be using NTLM? Log Name: System Source: LsaSrv Date: 3/27/2020 12:03:44 AM Event ID: 6038 Task Category: None Level: Warning Keywords: Classic User: N/A Computer: serverVM1.domain.local Description: Microsoft Windows Server has detected that NTLM authentication is presently being used between clients and this server. This event occurs once per boot of the server on the first time a client uses NTLM with this server. NTLM is a weaker authentication mechanism. Please check: Which applications are using NTLM authentication? Are there configuration issues preventing the use of stronger authentication such as Kerberos authentication? If NTLM must be supported, is Extended Protection configured? Details on how to complete these checks can be found at http://go.microsoft.com/fwlink/?LinkId=225699.
