Trouble loading a driver

[Mattzimmerer]

I'm trying to write an exe to load my driver into the kernel, I'm getting an error ERROR_PATH_NOT_FOUND. I know my sys file is in the at this path, what am I missing?

// Loader.cpp : Defines the entry point for the console application.
//

#include "stdafx.h"
#include <windows.h>
#include <stdio.h>

bool LoadDriver();

int _tmain(int argc, _TCHAR* argv[])
{
bool status;
status = LoadDriver();

if (status)
	printf("Driver load Succeeded!\\n");
else
	printf("Driver load Failed!\\n");

return 0;

}

bool LoadDriver()
{
wchar_t PATH[1024] = L"C:\\DLOADER\\DLOADER\\Debug\\target.sys";
wchar_t DRIVERNAME[1024] = L"target.sys";
printf("PATH: %ls\n", PATH);
printf("DRIVERNAME: %ls\n", DRIVERNAME);
SC_HANDLE sh = OpenSCManager(NULL, NULL, SC_MANAGER_ALL_ACCESS);
if(!sh)
return false;

SC\_HANDLE rh = CreateService(sh,
	DRIVERNAME,
	DRIVERNAME,
	SERVICE\_ALL\_ACCESS,
	SERVICE\_KERNEL\_DRIVER,
	SERVICE\_DEMAND\_START,
	SERVICE\_ERROR\_NORMAL,
	PATH,
	NULL,
	NULL,
	NULL,
	NULL,
	NULL);

if(!rh)
{
	printf("CreateService Failed(error%i)\\n",GetLastError());
	if (GetLastError() == ERROR\_SERVICE\_EXISTS)
	{
		// service exists
		rh = OpenService(sh,
			DRIVERNAME,
			SERVICE\_ALL\_ACCESS);
		if(!rh)
		{
			printf("OpenService Failed(error%i)\\n",GetLastError());
			CloseServiceHandle(sh);
			return false;
		}
		else
			printf("OpenService Success\\n");
	}
	else
	{
		CloseServiceHandle(sh);
		return false;
	}
}
// start the drivers
if(rh)
{
	if(0 == StartService(rh, 0, NULL))
	{
		printf("StartService Failed(error%i)\\n",GetLastError());
		if(ERROR\_SERVICE\_ALREADY\_RUNNING == GetLastError())
		{
			// no real problem
		}
		else
		{
			CloseServiceHandle(sh);
			CloseServiceHandle(rh);
			return false;
		}
	}
	else
		printf("StartService Success\\n");
	CloseServiceHandle(sh);
	CloseServiceHandle(rh);
}
return true;

}

Here is the output:

PATH: C:\DLOADER\DLOADER\Debug\target.sys
DRIVERNAME: target.sys
CreateService Failed(error1073)
OpenService Success
StartService Failed(error3)
Driver load Failed!

Any help would be appreciated! Ohh and heres what those error codes are: ERROR_SERVICE_EXISTS = 1073 ERROR_PATH_NOT_FOUND = 3

You need to follow the procedure below: 1) Open SC Manager, 2) Open Service, // You need to move this step here before creating service. 3) Create Service.

Awesome... 5 days after I started I was successful at creating a kernel level driver that I can send commands to from the user mode... wow now I can actually start programming :laugh: ... Thanks man, that ended up not being the route I took but I got a basic understanding of the SCM now! ;P Now if I can just read from physical memory correctly without blue-screening my system.. I'm guesstimating a good 10 days... gotta love free time... :laugh:
