How to restart a running service?

[mattp14]

I've got a method I wrote with the intended purpose of restarting a service.

Since I can't find a restart() method of the ServiceController class, my approach was to stop the service and then start it using the stop and start methods. This doesnt seem to be working though...

Any thoughts? Below is the code I came up with...

As usual... thank you so much to those that are willing to help us newbs out



Public Function restartService(ByVal targetMachineName As String, ByVal srvcName As String)
Dim serv As New System.ServiceProcess.ServiceController(srvcName, targetMachineName)

For Each serv In System.ServiceProcess.ServiceController.GetServices()
If serv.ServiceName = srvcName Then
serv.Stop()
serv.WaitForStatus(ServiceProcess.ServiceControllerStatus.Stopped, System.TimeSpan.FromSeconds(45))
serv.Start()
Exit Function
End If
Next
End Function

Firstly check the CanStop properties just to make sure it's possible.

If serv.CanStop Then
   serv.Stop()
Else
   MsgBox("cannot stop service")
End If

It may also be a permissions issues. For example the service might be running under the System account whereas your application is running under Pleb user which means the application can call a Stop all it likes with no result though I would have thought it should return an error

That's the thing... i KNOW it's possible. And the username that's running the program has administrative priveleges too.

The reason i know it's possible, is that I can call the start and stop methods individually, but not together.

It's mind boggling!

Dim serv As New System.ServiceProcess.ServiceController(srvcName, targetMachineName)

For Each serv In System.ServiceProcess.ServiceController.GetServices()

FYI:
If the first line succeeds, there's no need to go through each service from GetServices().
