AT task scheduler

This is not the first time I used AT.exe on Windows NT/2000/2003 server. I got very frustrated when I run a simple AT < c:\at 10:00 /interactive notepad.exe > on Windows server 2003 to fire up a Notepad, it just not working. I login as Administrator to setup at the AT job. On the other hadn, one of the windows 2003 that I installed in a PC works.

I also tried the AT job setup with a ” /k ” for troubleshooting… not working either.

Any idea/ suggestion will be appreciated.
