We have numerous OES shares that give the student container Create and File Scan rights. Students can drop their assignments in these shared directories, but can't read or overwrite or delete other students' work. This has worked fine for us for many years.

However, starting with Client for OES 2 SP4 (IR5) and continuing with IR6, we find that when a student attempts to copy a file to such a share, it only creates a zero-byte file, and immediately prompts to say the file already exists: attempts by the student to overwrite fail. Note that with IR4, this works. Also note that with IR5 and IR6, this work for Windows 7 clients. It is only Windows 10 clients, with IR5 and IR6 that we have the problem.

Has anyone else seen this and/or know of a solution?
