Subject: [MS-CIFS] Trans2FindFirst/FindNext

Hi DocHelp people,

I a questions about windows client behavior involving SMB Transact2 FindFirst/FindNext, as described in MS-CIFS

We have a Windows 7 (x64) client that appears to be repeatedly requesting a directory listing when Windows Explorer is asked to show large directory on our server.  The directory has about 20,000 folders.

The only obvious difference we see when comparing with a Windows server (2k8r2) is that we return the directory contents in the order found on-disk (which is in general, not sorted).

I'd appreciate suggestions on how to track down what might be the reason for the Windows client repeating the findfirst/findnext
requests as we observe.   Should we provide a TTT from the windows
