MmIsThisAnNtAsSystem

Hi,

I have a Ndis IM Driver on NT4 SP5, but sometimes it crashes in
MmIsThisAnNtSystem+31c5,
mov EAX,[ECX] DS:C0001000= FFFFFFFF

How could this happen and usually waht is the cause?

Thank you and hope you can give some insight!

MmIsThisAnNtAsSystem+31c5 is definitely not in routine
MmIsThisNtAsSystem.
You haven’t symbols for NTOSKRNL loaded. Try to load it and be more
precise.
Also there is a difference between checked and free build environment.
Which of
them you use ?

Paul, thanks for reply, I am on a free build NT, only my device driver is a debug build, where can I find symbol for NT kernel itself?

Try microsoft ftp, I think there is for every service pack also archive
containing symbols. And NTOSKRNL.EXE is changed from SP to SP.
