Input from a text file

Below, I have posted the part of an inventory script that connects to WMI. Currently I have the script running as a logon GPO. I'd like to change it so I don't have to wait for a user to logon for me to update the inventory. I'd like to be able to connect to each computer remotely. From Microsoft, I got the following that I thought might help. It's not connecting remotely but it's how to read from a text file. Surely, where they say just type the following at the command prompt, they don't mean all the text below. I'm assuming there's been a typo. Can someone help clarify that for me. I'm getting a bit confused with this.

And now here's the script that reads the preceding file. To run this script, you don't need to use any command-line parameters; just type the following at the command prompt and press ENTER:

cscript ListServices.vbs.Const INPUT_FILE_NAME = "C:\Scripts\Computers.txt"
Const FOR_READING = 1
Set objFSO = CreateObject("Scripting.FileSystemObject")
Set objFile = objFSO.OpenTextFile(INPUT_FILE_NAME, FOR_READING)
strComputers = objFile.ReadAll
objFile.Close
arrComputers = Split(strComputers, vbCrLf)
For Each strComputer In arrComputers
Set objWMIService = GetObject("winmgmts:" _
& "{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")
Set colRunningServices = objWMIService.ExecQuery _
("Select * from Win32_Service")
For Each objService in colRunningServices
Wscript.Echo objService.DisplayName & vbTab & objService.State
Next
Next

PART OF THE INVENTORY CODE

'Change this to the UNC path where inventory files should be created
'Anyone running this script must have read and write access to the
'path.
strInvFilePath = "C:\test\"
'If each user will run this inventory file locally, do not change the value
'of strComputer.
strComputer = "."
'Connect to WMI
Set objWMIService = GetObject("winmgmts:\\" & strComputer & "\root\cimv2")
