Looks like necessary option... I have added this task into "to do" list.
On the other hand, usually you assign this action to some "windows" test, like NT Event Log or Performance Counter that establishes connecttion to remote system, right? In such case action will work fine.
Ok this is good to know and could be a good workaround.
In our case we reboot some machines after getting a special bad http content test. But executing a powershell script wich restarts the VM does the job for us now.
