That's why I added that no one from the samba team had acknowledged it--I
wasn't sure you guys were aware of it, just that some people were. I only
joined the samba list about 2 weeks ago (mainly in search of a solution for
this problem) yet I've seen four reports of this problem (including this one
and mine) or something similar.

Seems to be the same issue:

Also, searching Google reveals other reports of the same or similar issues
(some fairly old).

I can reproduce it on my machine. I only have the one Linux box and one
Windows box, but this problem has persisted for months while I've gone from
Redhat 9 to SuSE 9, through various kernel versions (all 2.4.*) and a
complete reinstall on the Windows side. (I'm running 3.0.1 now, btw, though
I original discovered the issue in 2.2.x)

It seems to happen fairly consistently, though it's worse at times than
others. The more files in a directory, the more likely it is to occur.

I filed a bug report which details some of my findings:
https://bugzilla.samba.org/show_bug.cgi?id=939

I hope it wasn't too rambling. Take this with several hundred grains of
salt, but it seems to me, from looking at Ethereal captures, that it could
actually be a problem on the Windows side. The XP box appear to, at random
times, skip a directory item on FIND_NEXT2 commands.

Also, Michael Pflüger reported that using CIFS solved the problem.
Unfortunately, I have no idea how to do that (though I did try, always
ending in a target server not found and error 22).
