Troubleshoot script for stopping/diabling services

Could someone please let me know how to modify this script for use on the local machine only.  I just need to disable the services on the local machine, not a remotely located.  I'm not sure what the syntax is to specify local machine.  Thank you.

' Note: Each Service is case sensitive.
arrServices = Array("Telephony","Windows Audio")
 
' Server to stop services on
strServer = "servername"
 
If Ping(strServer) = True Then
	For Each strService In arrServices
		Set objWMIService = GetObject("winmgmts:" _
			& "{impersonationLevel=impersonate}!\\" _
			& strServer & "\root\cimv2")
		Set colListOfServices = objWMIService.ExecQuery _
			("Select * from Win32_Service Where DisplayName='"& strService & "'")
		On Error Resume Next
		For Each objService In colListOfServices
			If Err.Number = 0 Then
				On Error GoTo 0
				If objService.State = "Running" Then
					objService.StopService()
					Wscript.Sleep 5000
				End If
				objService.ChangeStartMode "Disabled"
			Else
				Err.Clear
				On Error GoTo 0
				WScript.Echo strService & " service was not found on " & strServer
			End If
		Next
	Next
Else
	WScript.Echo strServer & " could not be pinged."
End If
 
''WScript.Echo "Script finished."
 
Function Ping(strComputer)
	Dim objShell, boolCode
	Set objShell = CreateObject("WScript.Shell")
	boolCode = objShell.Run("Ping -n 1 -w 300 " & strComputer, 0, True)
	If boolCode = 0 Then
		Ping = True
	Else
		Ping = False
	End If
End Function
