If a program does not start because the path to the program file is
incorrect or because you typed a command-line switch within quotation
marks, the following entry is added to the Schedlog.txt file when Task
Scheduler attempts to start the program
"<program name>.job" (<program file name>) <date> <time> ** ERROR **
Unable to start task.
The specific error is:
<error code>: The system cannot find the file specified.
Try using the Task page Browse button to locate the application.
where <program name> is the name of the program (for example, ScanDisk),
and <program file name> is the name of the program's executable file (for
example, Scandskw.exe).
To view the Schedlog.txt file, click View Log on the Advanced menu in Task
Scheduler.
