>>It worked on the machine I tested at home; try using 6 (drop the ForceIfHung flag, 0x10, from the flag mix) rather than 22, since that might not be in whatever version of the API you're using. It's a relatively late addition to the API.

The MSDN documentation on the Platform SDK entry for ExitWindowsEx(); the flag values are defined in WINBASE.H, and there were threads on this API call in the last few days that included the list of flags.

If this is NT, you may need to be running with a different set of permissions in order to get the API call to work - not all users and applications have the necessary permissions to force a reboot. You might want to check the return code from ExitWindowsEx (it will return a numeric value) and see what that value is.
