WMI scripting template that runs the script against each computer whose name was entered as a command-line argument (individual computer names must be separated by blank spaces). This script pings the relevant computer before trying to make a connection. To run the script, type the script name followed by the names of the computers you want to run the script against. For example: my_script.vbs atl-ws-01 atl-ws-2 atl-ws-03.
