Problem with HI and shutdown script

hello,

i want to shutdown a windows system when the HI detects suspect registry entries.

The problem now with Utility: Run a script is the following,

i have this command in the script content of the rule:

shutdown -s -f -t 0

this one shuts down the system fine when i open a command prompt.

But when it's triggered over the HI it opens the cli and just repeats the command over and over and nothing happens. It looks like it has not the rights to shut the system down.

What would be the best way to get this to work?

thanks.
