I'm currently talking to another computer to see what events they have occurring. I have setup a Wql Event query like so below:

   Console.WriteLine("Polling...")
    Try
        Dim query As New WqlEventQuery("SELECT * FROM Lnl_AccessEvent")
        Dim accessEventWatcher = New ManagementEventWatcher("SELECT * FROM Lnl_AccessEvent")
        accessEventWatcher.Start()
        accessEventWatcher.WaitForNextEvent()
        Console.WriteLine("AccessEvent Occured.")

    Catch ex As Exception
        Console.WriteLine(ex.Message + " " + ex.StackTrace)
    End Try

On the ".Start()" line, I get an exception stating "Invalid class" and "ManagementException". I know the connection is working since before this instance I'm able to connect and get the basic info from the remote computer's WMI, like IP address. The only solutions I have found is that has to do with my target build being only x86, but now it's at AnyCPU and still has this issue.

What is causing this error?

Is it case-sensitive, by chance? Try `lnl_AccessEvent` – Tony Hinkle May 21 '15 at 14:17
No luck with that sadly. I was copying the name from their user guide setup – Kat May 21 '15 at 14:23
