SFilter 2000

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.

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 xxxxx@microsoft.com.

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.

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:

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.

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

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.

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 xxxxx@microsoft.com.

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.
