We have an application running on a WinXP client pc. The WinXP OS sees the Samba share as NTFS, but the application does some file system checking of its own and sees the share as FAT. fstype = ntfs is set and I've tried every parameter I could find to make the share more 'DOS' compatible, but no luck. Any suggestions? The software vendor refuses to support Linux. I'd like to find a new vendor, but unfortunately this is specialized software. David
