>How do you go about turning a service OFF in VFP ( by using code ). And.... turn a Service back On ???

It is pretty much the same thing as in .NET. However, you would need to run a DOS command like this:

        ' Enable the task
        loProcessFile.cWorkingDirectory = "c:\Windows\System32"
        loProcessFile.cFileName = "c:\Windows\System32\sc.exe"
        loProcessFile.cArguments = "\\" + lcIP + " start """ + lcService + """"
        If Not loProcessFile.Process() Then
            cMessage = loProcessFile.cMessage
            Return False
        End If

That is .NET code but you can easily adjust as needed.
