How to force-stop Sanako Student using VbScript and WMI

We have been experiencing issues with the Sanako student becoming unresponsive in the Language Lab. This utility resets the student on the student computer:

'debug:
'on error resume next
Const HKEY_LOCAL_MACHINE = &H80000002
arrComputers = Array("LSS-NWX13PC06") 'update this thru scriptomatic.hta strComputer = "LSS-NWX13PC06" '01<-fails, 03<- works,
'Service Name
SrvName = "Sanako Helper" 'which format? example imapiservice is not in win xp services.msc
'Process Name
'ProcessName ="Student.exe" 'überflüssig

For Each strComputer  In arrComputers
'restart helper.exe
For Each strService In GetObject("winmgmts:{impersonationLevel=impersonate}!\\" & strComputer).InstancesOf ("win32_service")
'   Set objWMIService = GetObject("winmgmts:{impersonationLevel=Impersonate}!\\" & strComputer & "\root\CIMV2")
'   Set colItems = objWMIService.ExecQuery("SELECT * FROM Win32_Service", "WQL", wbemFlagReturnImmediately + wbemFlagForwardOnly)

If strService.Name = SrvName Then
If strService.State = "Running" Then
WScript.echo "Shutting down '" & strService.Name & "' Service"
strService.StopService
wscript.sleep 5000
strService.StartService
WScript.echo "ReStarting '" & strService.Name & "' Service"
Else
strService.StartService
wscript.echo "Starting '" & strService.Name & "' Service"
End If
End If
Next 'service

'restart student.exe
'find path for starting
Set objRegistry = GetObject("winmgmts:{impersonationLevel=impersonate}!\\" & strComputer & "\root\default:StdRegProv")

strValueName = "InstallPath"
objRegistry.GetStringValue HKEY_LOCAL_MACHINE,strKeyPath,strValueName,strValue 'GetDWORDValue method is not needed
WScript.echo "Registry BaseDir is '" & strValue & "'"

If IsNull(strValue) Then 'Empty means that the registry value exists, but is blank; Null means that the registry value doesn’t exist.

strStudentCommandline = strValue & "\Study\Student\Student.exe"
End If
WScript.echo "strStudentCommandline is '" & strStudentCommandline & "'"

'do you have to do the same for vieostreamer window?

For Each strProcess In GetObject("winmgmts:{impersonationLevel=impersonate}!\\" & strComputer).InstancesOf ("win32_process")
'   Set objWMIProcess = GetObject("winmgmts:{impersonationLevel=Impersonate}!\\" & strComputer & "\root\CIMV2")

If strProcess.CommandLine = strStudentCommandline Then
strProcess.terminate
WScript.echo "Terminating '" & strProcess.CommandLine & "'"
wscript.sleep 5000
End If

'todo: remote

'todo: Processes launched by WMI can NEVER be visible. They run in their own windowstation, the same as window services.

Ret = WshShell.Run(strStudentCommandline, 3, True) 'bWaitOnReturn Optional. Boolean value indicating whether the script should wait for the program to finish executing before continuing to the next statement in your script. If set to true, script execution halts until the program finishes, and Run returns any error code returned by the program. If set to false (the default), the Run method returns immediately after starting the program, automatically returning 0 (not to be interpreted as an error code

If ret <> 0 then
wscript.echo "error starting "&  strStudentCommandline

End if
Next 'process running
Next 'strComputer

UPDATE: I haven now also coded  a similar utility in AutoIt, hopefully easier to use.
