You haven’t recently upgraded to a newer version of HaneWin, have you? Or removed it and reinstalled? I had some very weird stuff happening with HaneWin a month or two back, which turned out to be the result of some settings that had been added since the last time I had installed it.
If I recall correctly, the two that were causing most of the problems were on the “Server” tab in the control panel app: make sure “Use Windows file ID as inode on NTFS volumes” is not checked, and set the extended character set to UTF-8.
