SFilter 2000

OSR_Community_UserOSR_Community_User Member Posts: 110,217
Does anyone have the source for the SFilter example? I need to compare it
with my own driver and see if there are changes that may explain the system
hang I keep seeing when my driver is loaded in Win2k. Sadly, I need to do
this before the end of the week, which means I have no time to purchase the
whole IFS kit.

TIA.

    SFILTER for NT 4.0- is crap. They have amde some attempts to fix the bugs in
    the 2k version, but it still leaves a lot to be desired.

    The problem with SFilter is that it can not distinguish between the file
    system control device and the volume devices. This causes BSOD in some cases
    when trying to forward requests. It is totaly wrong.

    SFILTER from Nagars book is a better.

    I can not comment on whether these issues have been resolved in 2k becuase I
    use my own framework now, so I have not had the opportunity to check the 2k
    SFilter sources. Pardon my comments if these issues have been fixed.

    David,

    I believe the problems with SFilter that Jamey mentioned have been fixed in
    the Windows 2000 IFSKit. The IFSKIT also contains a new filter sample
    called FileSpy as well as a lot of new documentation.

    If you do encounter issues with the new version of the IFS kit please send
    your comments to [email protected]

    Also, the http://www.microsoft.com/hwdev/ntifskit/ntupto2k.htm website
    describes 'Potential issues involved in updating Windows NT IFS drivers to
    Windows 2000'. This should be helpful in working through your issues.

    You could also look at www.osr.com and www.systernals.com for information
    and examples of working file system filters.

    Thanks Neal I will check out the resources you talked about.

    How much is the IFSKit. I don't have it yet. I thought it came with
    the MSDN subscription I just ordered but I could be wrong.

    The IFSKit does not come with MSDN. It is something that has to be
    purchased separately. All of the latest information about the IFSKit,
    including how to order it and its price, can be found at:

    Thanks Neal I will check out the resources you talked about.

    How much is the IFSKit. I don't have it yet. I thought it came with
    the MSDN subscription I just ordered but I could be wrong.

    David,

    I believe the problems with SFilter that Jamey mentioned have been fixed in
    the Windows 2000 IFSKit. The IFSKIT also contains a new filter sample
    called FileSpy as well as a lot of new documentation.

    If you do encounter issues with the new version of the IFS kit please send
    your comments to [email protected]

    Also, the http://www.microsoft.com/hwdev/ntifskit/ntupto2k.htm website
    describes 'Potential issues involved in updating Windows NT IFS drivers to
    Windows 2000'. This should be helpful in working through your issues.

    You could also look at www.osr.com and www.systernals.com for information
    and examples of working file system filters.

    The problem with SFilter is that it can not distinguish between the file
    system control device and the volume devices. This causes BSOD in some cases
    when trying to forward requests. It is totaly wrong.

    SFILTER from Nagars book is a better.

    If you're stuck with your time pressures then you'll have to consider the
    IFSKit for your next project. Shipping of the kit is notoriously
    slow. Having started a new job and persuaded them to buy the kit, we're at
    5 weeks and counting.

    I never had these problems when ordering from within the US.

    Mark.

    Hi,

    sorry, perhaps I missed something in the list: I have the IFS Kit for Win
    2000 Beta 3. I waited for that one 2 months. Is there a new version
    available for Win 2000 Release (?), and if yes: do I have to purchase it
    again?

    thanks
    Frank Friemel
