minifilter & network file system

NTFSD
1

Hello,

my minifilter attaches every volume that currently exists in the system (including \Device\LanmanRedirector). PreCreate callback is called for every file I work with (fltObjects->FileObject->FileName is filled with the right name) - there’s no problem with this. If I try to open a file (e.g. \Device\LanmanRedirector\SHARED_PC\Sources\setup.exe) I get only “\Device\LanmanRedirector\SHARED_PC\Sources” in fltObjects->FileObject->FileName - but there will never appear “setup.exe” or other files, only directory names.

What could be wrong ?

thanks,
Petr Kurtin

Petr,

Have you tried the RelatedFileObject field of the FileObject? If
setup.exe is being opened relative to an already opened file (ie
"\Device\LanmanRedirector\SHARED_PC\Sources") then you'll need to check
it.

Petr,

What do you mean when you say "If I try to open a file". Do you mean from your filter? What API are you using to open it with? If you are opening it, why are you doing the open so you see your own creates? In general we wants opens from a filter to be targeted to the filters below them.

Please clarify what is going on.
