Hi John,

Sorry, I didn't see your previous response.
If you send me the test program and the network captures
I'll take a look at it.

Hello Joyce,

Have you had a chance to look at this case sensitivity issue?
I provided the test application and have the network trace available if you 
need it.

Hi Joyce,

We cannot reproduce it with the 'dir' windows command either, because 'dir' issues a 
"FIND_FIRST2" SMB command on the underlying path before requesting the file 
But you can do it with this small application, which just checks if a file 
exists (returns true or false). Here is how:
First, let's assume there is a file named \\filer\arch\myfolder\myfile.TXT 
stored on the ZFS NAS. This file has *not* been accessed by a Windows client 
"testcifs.exe \\filer\arch\myfolder\myfile.txt"  will fail.
then "testcifs.exe \\filer\arch\myfolder\myfile.TXT"  will work.
then "testcifs.exe \\filer\arch\myfolder\myfile.txt"  will work.

I have a network trace I can send you directly if you want.

Hi John,

We have been trying to reproduce this in-house but have so far been
unsuccessful. Would you mind providing us with binary network captures
of each of the steps:

1. dir \\filer\arch\myfolder\myfile.TXT failing 2. dir
\\filer\arch\myfolder\myfile.txt working 3. dir \\filer\arch\myfolder
4. dir \\filer\arch\myfolder\myfile.TXT working

What version of Windows are you running on your client?

Thanks Alan for the reply.
Could you explain how lookuppnvp is being used
The behavior I am describing is intermittent
somewhat. We are trying to narrow down what's happening.
Direct access to a file for the first time from a
client seems to be case sensitive. Example:
dir \\filer\arch\myfolder\myfile.TXT fails.
dir \\filer\arch\myfolder\myfile.txt works.

As soon as you issue "dir \\filer\arch\myfolder\",
the case sensitivity goes away and "dir
\\filer\arch\myfolder\myfile.TXT" starts working.
