schtask interactive command problem

Hi,

I am having a problem creating an interactive task that runs as either the system account or a specified domain account.

The task will run, but it will not show interactively for the currently logged on user.

On Windows XP, I can use a command such as this:

at 23:30 /interactive /every:M,T,W,Th,F,Sa,Su c:\batch\overnight.cmd

This will install our interactive nightly shutdown task that allows the user to pause, cancel or continue a shutdown. I do not use schtask as it won't run the command interactively.

If I run this on Windows 7 I get:

Warning: Due to security enhancements, this task will run at the time expected but not interactively.

So, I try to use schtask instead like this:

schtasks /create /TN "Nightly Shutdown Task" /tr "C:\Batch\Overnight.cmd" /sc daily /st 23:30:00 /RU CTSYNZ\PCTasks /RP sksaTCP /s %COMPUTERNAME%

This creates the task, but it still will not run interactively unless I am actually logged on as the user specified by /RU.

I have tried the local system account with no luck and all manner of combinations but I just can not get a task to run on Windows 7 interactively as another user.

Can anyone suggest how to do this? Is it even possible or is this another feature we have lost?

Thanks,

Rob
