WMI: VBscript to enumerate all processes on a computer

Ok, let’s put in another one..
The script creates a list of all prcesses on a computer.
Default computer is the local machine.
When the dot is replaced by another machine name the script works against that machine.
There are some conditions that must be met:

the script must be run with administrative credentials
the firewall of the remote machine needs the following ports opened for WMI: TCP 135, TCP 4168 and
UDP 9256

Follow the next steps to make and run the script (admin rights needed):

open your favorite text editor (mine is notepad++)
copy and paste the script into the editor (delete the line numbers)
save the script (for example c:templistprocesses.vbs)
open a command prompt
go to “c:temp”
give “cscript listprocesses.vbs” (without quotes) and enter

The script:

' Name : listprocesses.vbs
' Description : script to enumerate all processes on a computer
' Author : dirk adamsky - deludi bv
' Version : 1.00
' Date : 03-02-2010
' Level : beginner

strComputer = "."
Set objWMIService = GetObject("winmgmts:{impersonationLevel=impersonate}!\" & strComputer & "rootcimv2")
Set colItems = objWMIService.ExecQuery("Select * from Win32_Process")
For Each Item In colItems
	Wscript.Echo Item.Name
Next
Set colItems = Nothing
Set objWMIService = Nothing

As said earlier: when you have questions/problems please give a reply.

Happy scripting.
