Stop Service

NTDEV
1

Hello everyone !!
I have a problem
Since i am newbie to this driver development,
i hope i can get some answers without any frustration
I have a legacy driver
i want to load the driver, and note down the debug information
i have created some services and made some registry entries
i am able to install and start the service
but not able to stop the service

I have defined SERVICE_ALL_ACCESS but could not get to know how i could
not stop the service
when i try this through net stop…it gives a message saying… U dont have
access to stop or pause the service
my code looks somehow like this …

BOOL InstallFunc(IN SC_HANDLE SCManager, IN LPCTSTR DriverName, IN LPCTSTR
DriverBinary)
{
SC_HANDLE SCService;

printf(“\n Entering InstallFunc() “);
printf(”\nthe DriverName is %s”, DriverName);
printf(“\n the DriverBinary is %s”,DriverBinary);
SCService = CreateService(SCManager,DriverName, DriverName,
SERVICE_ALL_ACCESS, SERVICE_KERNEL_DRIVER,
SERVICE_DEMAND_START, SERVICE_ERROR_NORMAL,
DriverBinary, NULL, NULL, NULL, NULL, NULL );
if (!SCService)
{

return FALSE;

}

CloseServiceHandle(SCService);

return TRUE;
}

BOOL StartFunc(IN SC_HANDLE SCManager, IN LPCTSTR DriverName)
{
SC_HANDLE SCService;
BOOL bStart;
SCService = OpenService(SCManager,DriverName,SERVICE_ALL_ACCESS);
if (!SCService)
{
printf(“\n Service cannot be opened”);
return FALSE;
}

bStart = StartService( SCService, 0, NULL )
|| GetLastError() == ERROR_SERVICE_ALREADY_RUNNING
|| GetLastError() == ERROR_SERVICE_DISABLED;

if (bStart)
{
printf(“\n The Service is started”);
}

CloseServiceHandle(SCService);

return bStart;
}

BOOL StopFunc(IN SC_HANDLE SCManager, IN LPCTSTR DriverName)
{
SC_HANDLE SCService;
SERVICE_STATUS schStatus;
BOOL bStop;

SCService = OpenService(SCManager, DriverName,SERVICE_ALL_ACCESS ); if
(SCService==NULL)
return FALSE;

bStop = ControlService(SCService, SERVICE_CONTROL_STOP,
&schStatus );

if (bStop)
{
printf(“\n Service Stopped”);
}

CloseServiceHandle(SCService);
return bStop;
}

i am sorry , if i am asking something silly
but pls help me out

thanx in advance

One reason could be that your legacy driver does not have an unload routine.

Your driver must have an Unload routine implemented if you want it to be
stoppable by “net stop”.

Are you talking about a service or a driver? These are two different things.
Your kernel driver must have an unload routine in order to support a stop
service request. You do not have to write a program to use the service
manager api to load and unload your driver. Use a command window and the
commands ‘net start driver_service_name’ and ‘net stop driver_service_name’.
