Network security: LAN Manager authentication level This security setting determines which challenge/response authentication protocol is used for network logons. This choice affects the level of authentication protocol used by clients, the level of session security negotiated, and the level of authentication accepted by servers as follows: Send LM NTLM responses: Clients use LM and NTLM authentication and never use NTLMv2 session security; domain controllers accept LM, NTLM, and NTLMv2 authentication. Send LM & NTLM - use NTLMv2 session security if negotiated: Clients use LM and NTLM authentication and use NTLMv2 session security if the server supports it; domain controllers accept LM, NTLM, and NTLMv2 authentication. Send NTLM response only: Clients use NTLM authentication only and use NTLMv2 session security if the server supports it; domain controllers accept LM, NTLM, and NTLMv2 authentication. Send NTLMv2 response only: Clients use NTLMv2 authentication only and use NTLMv2 session security if the server supports it; domain controllers accept LM, NTLM, and NTLMv2 authentication. Send NTLMv2 response only
efuse LM: Clients use NTLMv2 authentication only and use NTLMv2 session security if the server supports it; domain controllers refuse LM (accept only NTLM and NTLMv2 authentication). Send NTLMv2 response only
efuse LM & NTLM: Clients use NTLMv2 authentication only and use NTLMv2 session security if the server supports it; domain controllers refuse LM and NTLM (accept only NTLMv2 authentication). Important This setting can affect the ability of computers running Windows 2000 Server, Windows 2000 Professional, Windows XP Professional, and the Windows Server 2003 family to communicate with computers running Windows NT 4.0 and earlier over the network. For example, at the time of this writing, computers running Windows NT 4.0 SP4 and earlier did not support NTLMv2. Computers running Windows 95 and Windows 98 did not support NTLM. Default: Send LM & NTLM responses on server. Undefined on workstations.
