Thanks ! But I am looking for the program/API used by a Windows client that results in a SMB_FIND_FILE_BOTH_DIRECTORY_INFO sent to Windows CE during your testing using Windows client.

I will ask him.

Have you observed that the same Windows client sends the different information level while connecting to different server ? The client (redirector) maps the application-provided [MS-FSCC] information levels to a SMB information Level. SMB_FIND_FILE_BOTH_DIRECTORY_INFO is mapped to FileBothDirectoryInformation passed from the application. I just want to check to see how this is passed from the application. > > Thanks! > > Hongwei > > > -----Original Message----- > From: Steve French [mailto:smfre...@gmail.com] > Sent: Wednesday, August 24, 2011 4:23 PM > To: Hongwei Sun > Cc: Edgar Olougouna; p...@tridgell.net; cifs-proto...@samba.org; MSSolve Case Email > Subject: Re: [REG:111081664438980] RE: [cifs-protocol] Level 257 FindFirst rejected by some Windows servers even though NTLM > > On Tue, Aug 23, 2011 at 10:43 PM, Hongwei Sun <hongw...@microsoft.com> wrote: >> Steve, >> >> Windows CE is not within the scope of protocol documentation, such as MS-SMB and MS-CIFS.
