Disaster Recovery Console on winXp/w2k/w2k3

Trik ini sengaja dibikin sticky krn sering banget ada pertanyaan “knapa klo saya mau merepair windows dgn opsi “R” pd setup instalasi kok ndak bisa masuk,padahal password sdh benar ?” …

hal itu dikarenakan windows mengadopsi sistem LMHash dan NTHash yg mendekripsi (mengubah acak menjadi kode lain) password administrator…! nah trik ini dilakukan sebelum kerusakan windows terjd,sehingga opsi R tak akan memninta pass lagi dan lsg menjalankan repairing dgn mengcopy balik file2 system ke direktori windows dan memperbaiki MBR…

he recovery console is a command line environment that is used to recover from system problems. This setting controls whether the administrator account will be logged on automatically or be required to enter a password when the recovery console is invoked during startup.

Open your registry and find the key below.

Create a new DWORD value, or modify the existing value called ‘SecurityLevel’ using the settings below

Settings:
System Key: [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Setup\
RecoveryConsole]
Name: SecurityLevel
Type: REG_DWORD (DWORD Value)
Value: (0 = require password, 1 = no password)

How to recover from a corrupted registry that prevents Windows XP from starting

Jika XP gak bisa booting krn error spt ini:

• Windows XP could not start because the following file is missing or corrupt:
\WINDOWS\SYSTEM32\CONFIG\SYSTEM
• Windows XP could not start because the following file is missing or corrupt:
\WINDOWS\SYSTEM32\CONFIG\SOFTWARE
• Stop: c0000218 {Registry File Failure} The registry cannot load the hive (file):
\SystemRoot\System32\Config\SOFTWARE or its log or alternate
• System error: Lsass.exe
When trying to update a password the return status indicates that the
value provided as the current password is not correct.

1. Insert the Windows XP startup disk into the floppy disk drive, or insert the Windows XP CD-ROM into the CD-ROM drive, and then restart the computer.
Click to select any options that are required to start the computer from the CD-ROM drive if you are prompted to do so.
2. When the “Welcome to Setup” screen appears, press R to start the Recovery Console.
3. If you have a dual-boot or multiple-boot computer, select the installation that you want to access from the Recovery Console.
4. When you are prompted to do so, type the Administrator password. If the administrator password is blank, just press ENTER.
5. At the Recovery Console command prompt, type the following lines, pressing ENTER after you type each line:

md tmp
