WMI scripting template which prompts you to enter (via StdIn) the name of the computer you want to run the script against. This script prompts you to enter a user name and password to be used when connecting to the remote computer; the script uses ScriptPW.dll to mask the password so that it does not appear on screen. The script also pings the relevant computer before trying to make a conenction. The script requires Windows Script Host 5.6 and must be run under Cscript.exe. The script runs only on Windows XP and Windows Server 2003, because those are the only two operating systems that support ScriptPW.
