Background.  I've not seen any documentation that suggests that the Task 
Scheduler defaults change thought.

Still seems odd that it's not visible/obvious in the GUI tbh.

Is the server configured to favor foreground applications or background tasks?

Turns out that the Windows 2008 Task Scheduler starts tasks at a lower than 
normal priority by default.

Best of all you can’t see or change this through the GUI, you have to export 
the task to an XML file, edit the priority in the XML file, then import it 
again.

Again, I’m personally patchy on the details as I’ve not been given many yet, 
but the guy who looks after this box will know more about the in’s and out’s of 
the apps running on it than I do.  He’s telling me all things are equal other 
than the way he’s calling the task, which for now I shall take his word on.

Is there a time differential?  Are you running the batch file at the same time 
as it would run as a scheduled task?  What happens when you run the batch file 
manually at that time?  What happens when you run the scheduled task 
immediately, not at it's normally scheduled time?

In a networked environment, it's rarely a "batch file that does 'stuff.'"  
There are a lot of variables left out.  The task may be irrelevant, the timing 
may not.  Or vice versa, or both, or neither!

Appreciate that, but I don’t know any more myself yet.  It’s a general “If 
you’re just running a batch file that does “stuff”, would you expect a 
scheduled task to behave differently to an interactive task if you hadn’t done 
something specific to tell it to?” for now.

I think we need more details to of the scheduled job as well as what the task 
does that might be different under a scheduler vs interactively.

We have a task (not one of mine so not sure entirely what it is/does that, when

The same task when run via a scheduled task, takes much longer to complete.  
Apparently it’s entirely reproducible and along the lines of a batch file being 
run.

Any ideas why this might be assuming the info I’m being given is accurate and 
it’s the exact same command/script is being called via the schedule task?

The OS is 2008 R2 SP1.

Thanks,
Paul
