Hi All,
I have an interesting thing going on, I am sure it used to work! Haven`t
changed a thing!! Honest 
Basically I have a filter driver denying access to a folder. I do this by
returning STATUS_ACCESS_DENIED in the IRP_MJ_CREATE dispatch. This is fine
locally but if I share the folder and access it from a remote machine the
create works!
I have checked and my filter is def. completing the irp with
STATUS_ACCESS_DENIED.
If I run filespy from IFS kit I see a flurry of pipe stuff going on though.
Am I missing something really stupid here?
Remote machine is XP, machine denying access (with filter driver on) is W2k

Are you denying the right folder, and are you sure you’re not experiencing
some caching problems?

Hi Dejan,
It is definitely the correct folder, as to whether I am experiencing caching
problems, how do you mean?

Look at FastIO functions, more specifically FastIoQueryOpen.

Probably you don’t recongize that create request is for protected folder
when RelatedFileObject != NULL.

To answer the comments on this topic so far, here goes.
-
I Handle relatedfileobject != NULL correctly and I intercept the create
correctly, i even complete the irp with access denied but this is never
reflected back to remote machine.
-
All FastIo paths seem to be correctly handled. In the case of
FastIoQueryOpen i return FALSE if i am attached to the device, this then
makes the system issue a IRP_MJ_CREATE (Which I see)

Ben,
I’ve tried my FP in the scenario you mentioned (XP accessing 2K), and
didn’t notice the problem. How is your network configured? Is the folder set as
Offline, maybe?
Regards, Dejan.

Hi all,
Ignore my brain deadness on this one! Now fixed the problem, and thanks
Alexei. I was handling related fileobject not correctly!
Ben goes and hides under rock for being so stupid…
