Identifying the current logged in user of a remote host

Here's a short and simple script to check for the currently logged-in user of a remote computer. This script has been tested on Windows XP and Vista; it may or may not work for older Windows OSes. Save the script as check-user.vbs and pass the remote host (or IP address) as an argument when launching the script (ie, check-user.vbs remote_host). You have to be an administrator of the remote machine being queried in order for the script to run properly.
