Stopping my ATL service failed

Hi,

I've created a ATL service in VC++ (unmanaged code) on Visual Studio 2005.
Everything works fine.

But I still have a problem to stop my service.

During its termination, my service needs time to communicate with external
components (about 5 minutes).

When I stop my service from the "Control manager", my service enters in a
STOP_PENDING state. I start a independant thread which refresh its status by
calling regularly SetServiceStatus.

But the "Control Manager" generates a 1053 error after a timeout of about 2
minutes.

After several days of work, I can't find the reason, so need help.

For information, there is my code:

void CMyServiceModule::OnStop()
{
      this->LogEvent(_T("SERVICE_STOP_PENDING"));
      m_status.dwWaitHint = 10000;
      m_status.dwCheckPoint = 1;
      SetServiceStatus(SERVICE_STOP_PENDING);

      _beginthread( StopFunct, 0, (void *) this );

      // PostThreadMessage(m_dwThreadID, WM_QUIT, 0, 0);
}

void StopFunct( void *ch )
{
      CMyServiceModule *pThis= (CMyServiceModule *)ch;

      DWORD dwStart = GetTickCount();
      dwStart += 300000;
     while (dwStart>GetTickCount()) {
           pThis->m_status.dwWaitHint += 10000;
           pThis->m_status.dwCheckPoint++;
           pThis->SetServiceStatus(SERVICE_STOP_PENDING);
           Sleep(3000);
     }

     PostThreadMessage(pThis->m_dwThreadID, WM_QUIT, 0, 0);
}

I used the SetServiceStatus which came from the parent class
(CAtlServiceModuleT):

void CAtlServiceModuleT::SetServiceStatus(DWORD dwState) throw()
{
    m_status.dwCurrentState = dwState;
    ::SetServiceStatus(m_hServiceStatus, &m_status);
}

Thanks in advance....
