How to import hashes using pwdump2 and pwdump3/pwdump3e in localized versions of Windows NT/2000/XP/2003?

In pwdump2 and pwdump3/pwdump3e programs are some errors, that do not allow import hashes from localized versions of Windows NT/2000/XP/2003 (see article Theory and practice of password auditing and recovery in Windows NT/2000/XP/2003).

pwdump2 without Active Directory support (pwdump2-orig) don't have error and may be used. To use pwdump2 with Active Directory support (pwdump2) you need to replace samdump.dll with one from Data\pwdump2\samdump.dll. It comes in LCP package.

To use pwdump3 and pwdump3e you need to replace LsaExt.dll with Data\pwdump3\LsaExt.dll or Data\pwdump3e\LsaExt.dll files depending on which one you use.

Fourthly, use most powerful computer you can.

Fifthly, distribute brute force session.

Language pack contains .set character sets files, .vwl vowels file, .tbl transliteration tables files, .kbd keyboard layouts files.

To create new language pack you need to do following:
