Hi!
AFAIR the security is checked only during file open. So it seems this will
work for me…
No trojans! -) I’m trying to make my ASPI<->SPTI wrapper DLL work under
accounts that do not have administrator rights so the user cannot open
\.\C: and all stuff like that to send IOCTL_SCSI_PASS_THROGH[DIRECT] to
the device.
Regards,
Anton A. Kolomyeytsev
IIRC access rights check is skipped if request originator is in kernel mode
and this call should succeed (correct me if it is wrong).BTW, I’d like to see a good reason for something like this (i.e. violation
of NT security). Trojan support?Best regards,
