In order to use L0pht, the ___________ must be exported from Windows NT.

SAMBA is a software suite that allows interoperability between Windows and Unix/Linux systems, not a component that needs to be exported for L0phtCrack.

LDAP (Lightweight Directory Access Protocol) is a protocol for accessing directory services, not the database L0phtCrack extracts hashes from.

The Kernel is the core part of the operating system; exporting it makes no sense for password cracking with L0phtCrack.

L0phtCrack works by extracting the hashed passwords from the Security Account Manager (SAM) database, which stores user account information, including password hashes, on Windows NT systems. Therefore, the SAM file is the target that needs to be exported or accessed for the tool to function.

PDC (Primary Domain Controller) is a role a Windows NT server can play, but the SAM database within that server is the specific target, not the PDC role itself.
