I want to write a VBS script which will check if specific service is installed/exist or not locally.

If it is not installed/exist, script will display message (any text) and disabled the network interface i.e. NIC.

If service exist and running, NO Action. Just exit.

If service exist but not running, same action, script will display message (any text) and disabled the network interface i.e. NIC.

i have below given code which is displaying a message in case one service is stop but it is not -

1. Checking if service exist or not

2. Disabling the NIC

   strComputer = "."
   Set objWMIService = Getobject("winmgmts:"_
       & "{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")
   Set colRunningServices = onjWMIService.ExecQuery _
       ("select State from Win32_Service where Name = 'dhcp'")
   
   For Each objService in colRunningServices
       If objService.State <> "Running" Then
           errReturn = msgbox ("Stopped")
       End If
   Next
   

Please help. Thanks in advance.
