Dr. Watson for Windows NT is an application error debugger, which is a program that detects application errors, diagnoses the error, and logs the diagnostic information. The information obtained and logged by Dr. Watson for a computer running Windows NT is the information needed by technical-support groups to diagnose the application error. The DRWTSN32.LOG log file is created in the form of an electronic text file that can be delivered to support personnel by whatever method they prefer. You also have the option of creating a binary crash dump file that can be loaded into the Windows Debugger for debugging.
If an application error occurs, Dr. Watson for Windows NT will start automatically. To start it when no error occurs, to access the main dialog box, type DRWTSN32 at the command prompt or in the Run dialog box, (which can be accessed by clicking Run on the Start menu).
