The system process LSASS.EXE terminated unexpectedly with status code -1073741571. The system will now shut down and restart.
If you restart in Safe Mode, you may receive a message similar to:
Svchost.exe has generated errors and will be closed by Windows. You will need to restart the program. An error log will be created.
This behavior is symptomatic of a corrupted Winsock2 registry key.
To fix the problem:
1. Open a CMD prompt.
2. using REG.EXE on Windows 2000, from the Windows 2000 Support Tools,
or REG.EXE built into Windows XP, Copy / Paste each of the following lines into the CMD Window and execute it:
REG DELETE HKLM\SYSTEM\CurrentControlSet\Services\WinSock2 /f
REG DELETE HKLM\SYSTEM\ControlSet001\Services\WinSock2 /f
REG DELETE HKLM\SYSTEM\ControlSet002\Services\WinSock2 /f
REG DELETE HKLM\SYSTEM\ControlSet003\Services\WinSock2 /f
NOTE: You may receive a 'not found' error on one or more of these commands.
3. Shutdown and restart your computer.
NOTE: In Windows XP, I would use a Restore Point prior to the corruption.
