can't run script

Having a problem run this script

at 1am /every:Friday c:\windows\shutdown.exe /l

when I run it a black screen pop up and then disappears so I know the script is running but nothing is happen. I have ran it from the command line and it say access denial but I am in the local administrator group. I even put the domain users in the administrator group and still access denial. I have also turn off the UAC. Any ideals guys.

What kind of script is this?

-l = logoff user.

What is the top line of your script?

At the command prompt:

/t xxx Set the time-out period before shutdown to xxx seconds.
The valid range is 0-315360000 (10 years), with a default of 30.
If the timeout period is greater than 0, the /f parameter is
implied.

I'll leave the math up to you.

Or maybe there's a way to do it in Task Schedular.......

Forget the above you can do it in task Scheduler by creating a new task, if you have the script correct.

it create it in the task scheduler and tell window to shutdown

at(task scheduler) 1am (time 1:00am) /every:Friday(date every friday) c:\windows\shutdown.exe(shutdown window) /l(local users)

But, the script is not the problem, because I tried other script that work in xp but they won't work in window 7. I would think it would be a rights problem. and I know I can do it from the task scheduler but I am lazy and don't want to do a 1000 or so computer individual.

maybe you could try Sysinternals psshutdown.

You can download the whole suite here:

I am still getting access denial.

I figure it out. You have to turn the UAC all the way off and restart your computer.

probably because your computer is not join to a domain.
