This setting controls whether the password typed when accessing a file share is shown in clear text or as asterisks.

Key: [HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Policies\Network]
Value Name: HideSharePwds
Data Type: REG_DWORD
Data: (0 = disabled, 1=enabled)

Changing LAN Manager Authentication on Windows NT (Windows NT)
Windows NT supports two kinds of challenge/response authentication: LanManager (LM) and Windows NT (NTLM). LM authentication is not as strong as Windows NT authentication so some customers may want to disable its use, because an attacker sniffing the network traffic could attack the weaker protocol.
The implementation of the NTLM Security Service Provider (SSP) in Server Pack 4 has been enhanced to allow clients to control which variants of NTLM are used, and to allow servers to control which variants they will accept.
To change the type of authentication to be used modify the key below with the following values:
Level 0 - Send LM response and NTLM response; never use NTLMv2 session security
Level 1 - Use NTLMv2 session security if negotiated
Level 2 - Send NTLM response only
Level 3 - Send NTLMv2 response only
Level 4 - DC refuses LM responses
Level 5 - DC refuses LM and NTLM responses (accepts only NTLMv2)
Note: Currently only Windows NT 4.0 (SP4 and greater) support NTLMv2, before making any changes to this key please read the Microsoft Knowledge base article below.

Key: [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa]
Value Name: LMCompatibilityLevel
Data Type: REG_DWORD
Data: 0 (default) to 5 as defined above
