WMI - Check if service is running and start it

Hello,

I am trying to piece together a script that will do the following:

1. Check status of a service daily
2. Start the service if it is no running
3. Log the actions to a log file

I would run this as a scheduled task. I have the following pieces of WMI to:

1. check status of service:

strComputer = "."
Set objWMIService = GetObject("winmgmts:" _
& "{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")
Set colRunningServices = objWMIService.ExecQuery _
("SELECT * FROM Win32_Service WHERE Name = 'someService'")
For Each objService in colRunningServices
Wscript.Echo objService.DisplayName & ": " & objService.State
Next

> I would prefer not to have any messsage box appear

2. Start the Service:

Set objService = objWMI.Get("Win32_Service.Name='" & strService & "'")
WScript.Echo " Starting " & objService.Name
objService.StartService()

Any help to piece this together into a vbs script would be greatly appreciated!

Cheers!

You're on the right track. You have all of the code that you need to accomplish this, but you are taking a bit of a run-around approach.You have correctly made use of WMI to return an instance of a single service. Notice that colRunningServices does return a collection, but in this case, it only contains a single item since there can only be one service with a given name.This next bit of code is a standard coding convention for iterating through the items in a collection. You don't need to do this. Since you know that you're only dealing with a single item, you can simply reference that item directly.Next, you have some code that looks like this:This code uses WMI to return an object reference for a specific service. As you can see from the last line of code I used above, we already have this so there's no need to query WMI twice. Simply wrap this all up in an IF block to perform your logic.Voila! This code uses the existing service reference. If the service's status is not running and the service isn't starting, then we force it to start with the ServiceStart method.

So the complete code looks like this:
