Dr Watson


Dr. Watson is a program error debugger that detects and diagnoses program errors
and creates User.dmp and DrWtsn32.log files to contain the diagnostic data. In Windows
NT these files are stored in the %systemroot% folder.
In Windows 2000, these files are stored in the %systemdrive%\Documents and Settings\All
Users\Documents\DrWatson
folder. For Windows XP, these files are stored
in the %systemdrive%\Documents and Settings\All
Users\Application Data\Microsoft\Dr Watson
folder. The DrWtsn32.log file
is appended each time a program error occurs; the User.dmp file is overwritten
each time.

To turn off the Dr Watson debugger, apply the following Windows NT / Windows
2000 / Windows XP registry hack:

Hive: HKEY_LOCAL_MACHINE
Key: SOFTWARE\Microsoft\Windows
NT\CurrentVersion\AeDebug

Name: Auto
Type: REG_DWORD
Value: 0 disable
Value: 1 enable

To re-enable Dr Watson, you can change Auto back to 1 or from the command
line type drwtsn -i.

To change the folder for log files, apply the following Windows NT / Windows
2000 / Windows XP registry hack:

Hive: HKEY_LOCAL_MACHINE
Key: SOFTWARE\Microsoft\DrWatson
Name: LogFilePath
Type: REG_SZ

This is the registry key containing most
of the values for Dr Watson including AppendToLogFile,
CrashDumpFile
(change from default name user.dmp), CreateCrashDump, MaximumCrashes, SoundNotification,

creates a crash dump file after an application crash has occured :

The DumpAllThreads value controls whether Dr. Watson
should dump the contents of all threads during an application error :

The WaveFile value specifies the path and filename of
the wave file to be played during an application error :

Hive: HKEY_LOCAL_MACHINE

There are various debugger utilities besides Dr Watson. Lotus Notes replaces
Dr Watson with its debugger. To switch back to Dr Watson, should another
debugger be enabled, apply the following Windows NT / Windows 2000 registry
hack:

NT\CurrentVersion\AeDebug

Name: Debugger
