Thanks Thorsen, but I do not want to run the command manually from the command prompt; that's is exactly what I want Task Scheduler to do for me. The commend is a batch file that I have been running manually for a few years now (so that it is thoroughly tested), but I want to do it automatically with the T.S. To make it run manually with T.S. to test the task you click on Run, on the right column, under Selected Item. That's where the Command line window appears with a message, and nothing happens.
I have also looked up on Event Viewer, but There is not an event failure code number, it just says the task failed to run, and the History tab is virgin, so it doesn't even start. Then I seasrched on MS Technet and found some explications, but not what I need to know: the text of the message that I cannot read because its four or five lines just blink on the screen.
How can I read this, please?
