What operating systems use NTLM?
All supported Microsoft operating systems provide NTLMv2 authentication capabilities. Systems that are affected in a default configuration are primarily at risk, such as systems that are running Microsoft Windows NT 4, Windows 2000, Windows XP, and Windows Server 2003.
Is NTLM still supported?
Current applications. NTLM authentication is still supported and must be used for Windows authentication with systems configured as a member of a workgroup. NTLM authentication is also used for local logon authentication on non-domain controllers.
What is NTLM and how it works?
NTLM credentials are based on data obtained during the interactive logon process and consist of a domain name, a user name, and a one-way hash of the user’s password. NTLM uses an encrypted challenge/response protocol to authenticate a user without sending the user’s password over the wire.
How do I know if NTLM is enabled?
In the Computer Configuration -> Windows Settings -> Security Settings -> Local Policies -> Security Options section, find and enable the Network Security: Restrict NTLM: Audit NTLM authentication in this domain policy and set its value to Enable all.
What is NTLM authentication in Windows?
Windows Challenge/Response (NTLM) is the authentication protocol used on networks that include systems running the Windows operating system and on stand-alone systems. The Microsoft Kerberos security package adds greater security than NTLM to systems on a network.

Is Kerberos better than NTLM?
Security. – While both the authentication protocols are secure, NTLM is not as secure as Kerberos because it requires a point-to-point connection between the Web browser and server in order to function properly. Kerberos is more secure because it never transmits passwords over the network in the clear.
