NTFSD Folk:

I asked about this before but never got a response. FltSetSecurityObject
consistently fails, but ZwSetSecurityObject works fine. Any help?

I’m getting 0xC0000002 (STATUS_NOT_IMPLEMENTED) from FltSetSecurityObject.
This is on XP SP2, but I think it’s consistent on other platforms.

ZwSetSecurityObject works fine, even on Windows 2000 (in spite of the fact
that the documentation says “XP and higher” ).

Is this a known problem in FltSetSecurityObject? Any reason not to use
ZwSetSecurityObject regardless of the documentation?

Ken,

It turns out that this is a bug in the filter manager. The Flt routine
is properly generating an IRP_MJ_SET_SECURITY callback data structure.
I found that the underlying support routines which converts this to an
IRP is returning this error. For now the Zw routine should work fine.
I have filed a bug to get this fixed.

Thank you for reporting this,
