Good afternoon,

Thanks,

AFAIK this routine is not available on XP, the doc say’s

“This routine is available on Microsoft Windows Update Rollup for Windows
2000 SP4, Windows Server 2003 SP1 and later”

Welcome to the wonderful world of backwards compatifility and mini-filters.
Use ObReferenceObjectByHandle to get the file object after using
FltCreateFile

Thanks for the reply. I have XP SP2 machines that have the function and others that don’t. A completely clean machine with no updates applied does not have it. A machine that has all the updates applied has it.

So, I was wondering if someone has already suffered through applying the updates one at a time to find out which one it is.
