RE: Question on File System Filter driver on XP and W in2k

It is very normal for a filter driver to work on one system, but not on a
quite similar system, because there are lots of things to be different. Even
if you don’t see a chang, it might just be timing or a different hardware. A
thousand reasons for a driver to crash is an understatement. Obviously what
you’ve done was not a minor change at all. You should try to also use the
windbg of the ddk. It helped me a lot to see output of DbgPrint in realtime
on a second PC (using the serial null modem), just to understand what my
driver does, when it does. Together with the stack trace and all the options
it helps you to get as close to an error as possible. The DDK includes
perfect instructions on this.
