"PktContext is empty, no big_buf"

I have been developing a driver for NT using the NT DDK. I now have to
migrate it to Win2K and hope that it will be a trivial operation.

I start up Win2K and, before I start up OSRLoader, I start up DbgView
(v3.24) and, soon after, I start to get messages that say “PktContext is
empty, no big_buf” appearing, apparently randomly (25 over a three minute
period). At this stage, I have not even started OSRLoader, let alone my
driver.

So can anyone explain where is this coming from? I cannot find a possible
source in the work that I have been doing. Could this be something to do
with running v3.24 of DbgView on Win2K? If so, is there any other issues
that I need to be aware of when migrating from NT to Win2K. Or could it be
some other part of Win2K that is having problems and it’s output is
leaking into DbgView?

It’s not a showstopper, but it’s not very encouraging.

Any help would be appreciated,
Richard

Maybe some NDIS driver?
Scan the whole system32\drivers directory for the “PktContext” string.
