  • ???? 1 - ????? NTLM 2 ???? ??????? ??? ????? Clients use LM and NTLM authentication, and use NTLM 2 session security if the server supports it; domain controllers accept LM, NTLM, and NTLM 2 authentication.
  • Level 2 - Send NTLM response only. Clients use only NTLM authentication, and use NTLM 2 session security if the server supports it; domain controllers accept LM, NTLM, and NTLM 2 authentication.
  • Level 3 - Send NTLM 2 response only. Clients use NTLM 2 authentication, and use NTLM 2 session security if the server supports it; domain controllers accept LM, NTLM, and NTLM 2 authentication.
  • Level 4 - Domain controllers refuse LM responses. Clients use NTLM authentication, and use NTLM 2 session security if the server supports it; domain controllers refuse LM authentication (that is, they accept NTLM and NTLM 2).
  • Level 5 - Domain controllers refuse LM and NTLM responses (accept only NTLM 2). Clients use NTLM 2 authentication, use NTLM 2 session security if the server supports it; domain controllers refuse NTLM and LM authentication (they accept only NTLM 2).
A client computer can only use one protocol in talking to all servers. You cannot configure it, for example, to use NTLM v2 to connect to Windows 2000-based servers and then to use NTLM to connect to other servers. ?? ??????? ?? ?????? ???

You can configure the minimum security that is used for programs that use the NTLM Security Support Provider (SSP) by modifying the following registry key. These values are dependent on the LMCompatibilityLevel value:
  1. Start Registry Editor (Regedit.exe).
