Driver Entry Point Not Found

NTFSD
1

Hi,

I expect that asking this question will expose me as the newbie I am, but
here goes…

I have written a simple FSD that just watches all IO going through the
system. It works perfectly on 2000, but starting it on NT4 generates this
message:
Driver Entry Point Not Found
… could not locate the entry point _except_handler3 in driver
ntoskrnl.exe

What have I missed?

Thanks,
Adrian

Adrian,

This would indicate that you have built your driver with the Windows 2000
DDK (or IFS Kit) and are attempting to run it on NT 4.0. This does not
work. You need to use the NT 4.0 DDK to build an NT 4.0 compatible driver.

Thanks Tony, problem solved.

I dug up an old (April 2000) platform SDK CD as well as using the NT4 DDK.
I also noticed that SETENV.BAT in the DDK doesn’t work when the SDK is
installed in a directory with a long file name. A few double-quotes fixed
that problem.

Thanks for your help!

Hi Adrian,

how did you get *.pdb file for WinDbg with this NT DDK?
When I build my driver with IFS it’s ok, but with NT DDK I couldn’t get
this symbol file.

Thanks,
Kristian

Kristian,

I actually didn’t bother trying yet. I’ve developed and tested in Win2K.
The NT step is just a recompile. Sorry I can’t be more help. If I come
across the same problem later in my development cycle, then I may be
emailing you to ask if you solved it.
