NDIS Sample Driver - Access Denied

NTDEV
1

Hi All,

I am pretty sure that my problem is too easy to solve it, but I understand nothing.

I am using : WINDDK 7600.16385.0.
I am building the sample ndisprot 5x for Windows Seven. (7600.16385.0\src\network\ndis\ndisprot\5x\sys)
I am using the test ample program for this drivers 7600.16385.0\src\network\ndis\ndisprot\5x\test).

If I start the test program in non Adminstrator, I have an error (5) on CreateFile : Access Denied.

The inf file has no “security” informationin INF file. If I need to add this kind of information, how I can do this.

Thanks to all.
note: I do some research on the forum wihtout success

I assume that you have already started the driver using “net start
ndisprot”.

You can try a different SSDL in your call to IoCreateDeviceSecure:

SDDL_DEVOBJ_SYS_ALL_ADM_RWX_WORLD_RWX_RES_RWX

Good luck,

Did you look at the driver code? You are specifying that only system and
administrators can access your device.

If I start the test program in non Adminstrator, I have an error (5) on
CreateFile : Access Denied.
If you use CMD.exe to execute test.exe, maybe you need more privilege. Try run as Administrator!

Great ! Many thanks to Thomas Divine and Bill Wandel !
I am OK, if I read the source code, I am specifying that only system and
administrators can access your device. But as it is a sample it is not really me ;-).
I updated the source code:
before:
status = IoCreateDeviceSecure(pDriverObject,
0,
&ntDeviceName,
FILE_DEVICE_NETWORK,
FILE_DEVICE_SECURE_OPEN,
FALSE,
&SDDL_DEVOBJ_SYS_ALL_ADM_ALL
NULL,
&deviceObject);
After:
status = IoCreateDeviceSecure(pDriverObject,
0,
&ntDeviceName,
FILE_DEVICE_NETWORK,
FILE_DEVICE_SECURE_OPEN,
FALSE,
&SDDL_DEVOBJ_SYS_ALL_ADM_RWX_WORLD_RWX_RES_RWX,
NULL,
&deviceObject);

Now it is OK.

Many Many Many thanks.
