SYMPTOMS
You have a Briefcase folder, and a file in it has the synchronized copy on a Windows NT network share.

When you modify the file in the local folder, and synchronize it with the server copy, the synchronization status still shows, "Needs updating." When you synchronize it again, Briefcase offers to copy the file from the remote location, although the file time stamp is identical.

After Briefcase copies the file from the remote location, the synchronization status is correctly set to "Up-to-date."



CAUSE
After Briefcase copies the file to the server during the first update, it uses FindFirstFile to read back the file information. In some cases, the LAN Manager redirector runs this API before the file is closed. If this happens, the file size of the remote file is not correct and the synchronization status is not set correctly.

In a network trace, you can see a frame sequence like this between the client and server:

  SMB       C write, FID = 0x9804, Write 0x0 at 0x0000020E SMB      R write, Wrote 0x0 SMB      C transact2 Set file info, FID = 0x9804 SMB      R transact2 Set file info (response) SMB      C transact2 Findfirst, File = \Text2.txt SMB      R transact2 Findfirst (response) SMB      C close file, FID = 0x9804 SMB      R close file

In response to the Findfirst server message block (SMB), you will see an incorrect file size.
