Re: [ntfsd] Re: Question about R. Nagar's sfilter

> But do you mean that IoRegisterFsRegistrationChange() does not work as it is described in IFS DDK if it is not loaded at boot time?So if I want to filter a later mounted volume I have to intercept the mount IRP and attach the filter driver to the FSD manually?

When you intercept a mount request you are attaching to a volume

  • you are already attached to the FSD at that time, as otherwise you
    wouldn’t see a mount request.
    The IFS kit for Windows XP need not mention that
    IoRegisterFsRegistrationChange doesn’t work unless your driver is loaded
    at boot time, because this is so for Windows NT/2000 only - it does work
    on XP.

The other question is that I try to load R. Nagar’s sfilter at system boot time.But it result in my system crashing.I want to know is there anybody who succeeded in doing that? Or i have to do sth before I can do it?

If it doesn’t work for you, you made a change that made it crash

  • the SFilter works OK when loaded at boot time (which is when it must
    boot).
