Hi again,
When setting up scheduled tasks to run on an windows server, i've found it useful to wrap my executable with a batch file, which keeps track of logging all the console standard and error output. It redirects them to log files with a YYYYMMDD prefix, and deletes old logs too. The idea is that the scheduled task runs this batch instead of the executable directly:

md logs

echo ************************ >> logs\%date:~10,4%%date:~7,2%%date:~4,2%_MyJob.log
echo Starting - %date% %time% >> logs\%date:~10,4%%date:~7,2%%date:~4,2%_MyJob.log
MyJob.exe >> logs\%date:~10,4%%date:~7,2%%date:~4,2%_MyJob.log 2>&1
echo Ended    - %date% %time% >> logs\%date:~10,4%%date:~7,2%%date:~4,2%_MyJob.log
echo ************************ >> logs\%date:~10,4%%date:~7,2%%date:~4,2%_MyJob.log
