postoji mogućnost da je SAM fajl zaštićen...
On systems that do not use Active Directory, or SYSKEY, you may obtain password hashes directly from a password database file stored on the system -- the SAM file.
Note: this approach will not allow you to obtain password hashes from most Windows 2000 systems, as Windows 2000 uses SYSKEY by default. SYSKEY was introduced in Windows NT Service Pack 3, but was not turned on by default, so SAM access works on Windows NT systems unless SYSKEY was explicitly turned on. SYSKEY provides an additional layer of encryption to stored password hashes. Interestingly, you can't tell by looking at the SAM or at password hashes it contains whether they've been encrypted with SYSKEY or not. LC4 cannot crack SYSKEY-encrypted password hashes. This implies that if you do not have access to at least one administrator account on a Windows 2000 machine, you cannot obtain the password hashes required to run LC4. In such cases, you may benefit from a password reset utility.
