In the System option of Control Panel, there is a Recovery dialog box in which you make settings that control what happens in the event of a system lock-up. This section describes values for the Recovery dialog box, found in the following Registry path:
|
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\CrashControl
CrashDumpEnabled REG_DWORD 0 or 1
Specifies whether debugging information is to be written to a log file.
Default: 1 (enabled) for NTAS, 0 (disabled) for NT Workstation
LogEvent REG_DWORD 0 or 1
Tells the system to write events to a system log.
Default: 1 (enabled) for NTAS, 0 for NT Workstation
Overwrite REG_DWORD 0 or 1
Specifies whether an existing log file is to be overwritten by the new one.
Default: 1 (enabled) for NTAS, 0 (disabled) for NT Workstation
SendAlert REG_DWORD 0 or 1
Controls whether an administrative alert is sent.
Default: 1 (enabled) for NTAS, 0 (disabled) for NT Workstation
If Overwrite is disabled and the LogEvent is enabled, the system displays a message saying that the log is full. All further log attempts are ignored.
If this is unacceptable, create the CrashOnAuditFail value (REG_DWORD) in the following Registry path:
|
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa
Set CrashOnAuditFail to 1. Now when a log attempt fails, the system will halt and not reboot.
