Question on File System Filter driver on XP and Win2k

NTFSD
1

Hi All,
I have a File system filter driver(similar to Filemon). I have
created the registry entry so that the driver loads automatically (START =
2). After I put the .sys file in the specific image path and restart the
system, the system crashes.

I tried it on two win2k systems it crashed one system but is running
fine on the other.

Can anyone throw some light as to why such behaviour is seen. Is
there any way that I can understand the behaviour.

regards,
shivas

This is a driver that you are developing ??? There are hundreds and thousands of reasons why it might crash. From system to system the file system contents may be different, the driver’s that load could be different, different file system types, etc. etc. You need to provide specifics, and even then, you should hook up a debugger (and maybe a checked Windows 2000 build) and get the examine the crash. You should also consider getting symbols for your build, which can be done automatically by WINDBG through Microsoft’s symbol server. You can also do this in a post mortim way by using the crash dump that is generated when the system crashes, assuming of course your system if creating a crash dump.

Questions:

  1. what is the Windows 2000 configuration?
  2. what filter driver are you talking about? your own?
  3. what is your experience level with kernel debuggers, like WINDBG?
  4. have you done crash dump analysis?
