Windows NT Service

Hi,
I have got an MFC application developed in MSVC++ 6.0. I want this application to launch with any NT machine at boot and it should stay there as users LogOn/LogOff. In other words I want to use it as a NT service. I tried to convert this application into service but did not found it practical. Later I thought to call my executable from some other NT service program. I used some examples to create a sample NT service and called exe from there. Now sample service gets loaded after boot, but it never calls my application. I want to know what can be good way to do my job i.e. converting my app as service or call it from some other service. Please try to answer ASAP.

I think you can open your exe as service and select the boot time start,
so you application will start when boot and
work as service,
use the CreateService
