Titel:	Microsoft Windows: Network security: Do not store LAN Manager hash value on next password change
Zusammenfassung:	This policy setting determines whether LAN Manager is prevented;from storing hash values for the new password the next time the password is changed. Hash values are;a representation of the password after the encryption algorithm is applied that corresponds to the;format that is specified by the algorithm. To decrypt the hash value, the encryption algorithm must;be determined and then reversed. The LAN Manager hash is relatively weak and prone to attack;compared to the cryptographically stronger NTLM hash. Because the LM hash is stored on the local;device in the security database, the passwords can be compromised if the security database, Security;Accounts Manager (SAM), is attacked.;;By attacking the SAM file, attackers can potentially gain access to user names and password hashes.;Attackers can use a password-cracking tool to determine what the password is. After they have access;to this information, they can use it to gain access to resources on your network by impersonating;users. Enabling this policy setting will not prevent these types of attacks, but it will make them;much more difficult.;;(C) Microsoft Corporation 2015.
