cannot shutdown from “Unlock” dialog

I’m running Win2k Pro on a desktop, fairly new PC. Using Task Scheduler, I wake the computer up from Hibernation using a dummy task. At wakeup, I’m on the “Unlock Computer” dialog.

Few minutes after that, I run a script, and at the end of the script I shutdown the PC using:
shutdown.exe -r -f

All of this is done at the “Unlock Computer” dialog – and happens in the background using Task Scheduler (mstask.exe).

Problem is that the PC won’t shutdown, until I press Ctrl+Alt+Del, then Esc!!

Any solutions for this – one is that I shouldn’t enable locking of the PC after resuming from hibernation – but I want to keep it locked!

I’ve already tried some registry settings, no help. APM is enabled in BIOS (I think).
